Problem

Generate Code copies the request's method into the snippet exactly as it is held in memory. When that value is lower-case, the generated command is not runnable:

curl --request post --url https://api.example.com/users   # server responds 400

HTTP methods are case-sensitive tokens (RFC 9110 §9) and every IANA-registered method is upper case, so post is not POST. Strict servers and CDNs reject it. The request works inside Bruno but the snippet the user copies out does not, which is the worst shape for this bug — it looks like a server problem, not a Bruno one.

This affects every target, not just curl (wget --method post, the raw post /users HTTP/1.1 request line), because HTTPSnippet copies the HAR method through verbatim.

Two read paths let a lower-case verb reach the model:

  1. .bru response examples. parseBruRequest upper-cases the parent request's method, but hands the raw block header to bruExampleToJson — so an example inherits post where its parent correctly shows POST. A .bru block header is the verb and is lower-case by the format's convention, so this is reachable without hand-editing anything.
  2. .yml collections (the default format). The yml layer normalised in neither direction, so a lower-case verb in opencollection.yml survived every round trip and reached the snippet forever.

Fixes #9249

Fix

Normalise at the read boundary so the in-memory model is always canonical, rather than patching the snippet generator. That fixes Generate Code and everything else that renders the method verbatim, and it repairs existing collections on load without rewriting anyone's files — the canonical value is simply what gets written on the next save.

  • New shared normalizeHttpMethod helper in bruno-filestore/src/utils.
  • bruExampleToJson now normalises the inherited/own method, closing the parent-vs-example asymmetry.
  • parseHttpRequest normalises both the request and its examples; parseGraphQLRequest gets the same treatment, since it is the same class of hole.

Two things deliberately left alone:

  • toUpperCase(), not lodash _.upperCase — matching the comment already in parseBruRequest, because _.upperCase strips the special characters custom methods are allowed to contain (m-searchM SEARCH).
  • gRPC stores a case-sensitive fully-qualified path (/pkg.Service/Method) in the same field, so it is explicitly excluded.

I did not add write-side normalisation: it would rewrite users' committed collection files on save for no behavioural gain, and read-side alone already fixes the reported symptom.

Tests

Two new specs, 12 cases:

  • bru/tests/example-method-case.spec.js — example inherits the parent verb upper-cased (the reported path), example's own lower-case verb, already-upper-case left alone, custom m-search keeps its hyphen, missing verb falls back to GET, and a gRPC method path is untouched.
  • yml/method-case.spec.ts — same matrix driven end-to-end from opencollection.yml text through parseItem, covering the request, its examples, graphql, and gRPC.

Full bruno-filestore suite passes (28 suites, 259 tests). npx eslint on the changed files reports no new warnings.

Summary by CodeRabbit

  • Improvements
    • HTTP and GraphQL request methods are now consistently normalized to uppercase when importing collections and examples.
    • Missing HTTP methods default to GET.
    • Existing uppercase methods and custom HTTP method punctuation remain unchanged.
    • gRPC method paths retain their original case-sensitive formatting.
    • gRPC examples without a method now inherit the parent method path correctly.

HTTP methods are case-sensitive tokens (RFC 9110 S9) and every
IANA-registered method is upper case, so `post` is not `POST` to a strict
server. Bruno sends the request fine either way, but a lower-case verb that
reaches the model leaks into anything that renders the request verbatim -
most visibly Generate Code, which emits `curl --request post`.

Two read paths let a lower-case verb through:

- `.bru` examples. `parseBruRequest` upper-cases the parent request's method
  but hands the raw block header to `bruExampleToJson`, so an example
  inherits `post` where its parent shows `POST`.
- `.yml` collections. Neither `parseHttpRequest` nor `stringifyHttpRequest`
  normalised, so a lower-case verb in `opencollection.yml` survived every
  round trip.

Normalise at the read boundary instead, via a shared `normalizeHttpMethod`
helper, so the in-memory model is always canonical and existing collections
are fixed without rewriting anyone's files. `toUpperCase()` rather than
lodash's `_.upperCase`, which strips the special characters custom methods
are allowed to contain. gRPC keeps its case-sensitive
`/pkg.Service/Method` path untouched.

Walkthrough

The filestore now normalizes HTTP and GraphQL methods to uppercase, applies defaults for missing methods, and preserves case-sensitive gRPC method paths. YAML and BRU tests cover explicit, inherited, special, and missing method values.

Changes

Layer / File(s) Summary
Normalization utility
packages/bruno-filestore/src/utils/index.ts
Adds normalizeHttpMethod, which trims and uppercases methods and returns a fallback for empty values.
YAML method parsing
packages/bruno-filestore/src/formats/yml/items/parseHttpRequest.ts, packages/bruno-filestore/src/formats/yml/items/parseGraphQLRequest.ts, packages/bruno-filestore/src/formats/yml/method-case.spec.ts
YAML HTTP, GraphQL, and example methods use normalization. Tests cover casing, defaults, special methods, and gRPC paths.
BRU example parsing
packages/bruno-filestore/src/formats/bru/index.ts, packages/bruno-filestore/src/formats/bru/tests/example-method-case.spec.js
BRU examples normalize non-gRPC methods and preserve inherited or explicit gRPC method paths. Tests cover both behaviors.

Change: Bug fix · Severity of issue fixed: Medium

Merge Risk: ⚪ Minimal · up to e180d

This change canonicalizes HTTP methods to uppercase when reading Bruno collections, fixing generated code (curl/wget/etc.) that previously emitted lowercase verbs some servers reject, while correctly preserving gRPC's case-sensitive method paths including inheritance from parent requests. The reviewed evidence shows the implementation and tests align with this intent, so the change appears safe to merge.

Use single quotes for the test description.

The repository-wide JavaScript convention requires single-quoted strings. The import already ends with a semicolon, so no change is needed there.

Comment thread packages/bruno-filestore/src/formats/bru/index.ts
parseBruRequest passed `http.method` to bruExampleToJson for every request
type, but gRPC keeps its fully-qualified path under `grpc.method`. A gRPC
example that omitted its own method therefore fell through to the 'GET'
fallback instead of inheriting `/pkg.Service/Method` - the same
parent-vs-example asymmetry this branch fixes for HTTP verbs.

Closing in favour of #9250, which fixes #9249 and was opened first — I missed it when I picked up the issue.

One thing this PR also fixed that #9250 doesn't touch: a gRPC example with no method of its own inherits GET instead of the parent's method path, because parseBruRequest passes http.method to every example regardless of request type. The fix is still on this branch if it's wanted.
