Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.

In `@javascript/reactjs-todo-davinci/client/constants.js`:
- Line 29: The rawConfig constant assignment does not handle errors when parsing
process.env.SDK_CONFIG, which will cause the entire module to fail loading if
the JSON is malformed. Wrap the JSON.parse call in a try-catch block, and if
parsing throws an error, fall back to using sdkConfigJson as the default value.
This ensures the application can still initialize even when SDK_CONFIG contains
invalid JSON.

In `@javascript/reactjs-todo-davinci/playwright.config.ts`:
- Line 3: The import statement for testFidoConfig is triggering a no-unused-vars
lint error because the variable is only referenced in commented code and not
actively used. Either remove the import statement for testFidoConfig entirely if
it is not needed, or uncomment and properly integrate the code that uses
testFidoConfig so the variable is actively referenced in the configuration.

In `@javascript/reactjs-todo-davinci/README.md`:
- Around line 65-70: The README.md file contains an inconsistency in the
redirect URI configuration examples, showing
https://localhost:8443/callback.html in one location and
http://localhost:8443/callback.html in another. Update the redirect URI in the
OIDC configuration example to use the same protocol (http or https) consistently
throughout the entire README file to prevent configuration errors during user
onboarding.

In `@javascript/reactjs-todo-journey/client/constants.js`:
- Around line 31-33: The JSON parsing of environment variables can cause module
load-time crashes if the JSON is malformed. In
javascript/reactjs-todo-journey/client/constants.js lines 31-33, wrap the
JSON.parse call for import.meta.env.VITE_SDK_CONFIG in a try/catch block and
fallback to sdkConfigJson on parse failure. Apply the same guarded
parse/fallback pattern in javascript/reactjs-todo-oidc/client/constants.js line
28 for process.env.SDK_CONFIG to ensure both modules gracefully handle invalid
JSON without crashing at load time.
- Around line 35-40: The CONFIG object in both files unconditionally overwrites
the redirectUri property, ignoring any pre-configured value from rawConfig. In
javascript/reactjs-todo-journey/client/constants.js at lines 35-40, modify the
oidc.redirectUri assignment to conditionally use the value from
rawConfig.oidc.redirectUri when it exists, falling back to the
window.location.origin-based URL only when it is missing or undefined. Apply the
identical conditional fallback pattern to
javascript/reactjs-todo-oidc/client/constants.js at lines 30-35 so that any
configured redirect URI in rawConfig is preserved instead of being clobbered.

In `@javascript/reactjs-todo-journey/vite.config.js`:
- Line 44: The current code uses new URL(...).pathname to construct a file path
for the config.json file, which is unreliable on Windows and other platforms due
to leading slashes and unencoded characters. Import the fileURLToPath function
from the built-in url module and replace the pathname-based approach in the
optionalConfigJson call with fileURLToPath(new URL('./config.json',
import.meta.url)) to ensure the path works correctly across all platforms when
checked by existsSync.

Outside diff comments:
In `@javascript/reactjs-todo-davinci/client/context/oidc.context.js`:
- Around line 34-63: The useEffect hook starting at line 34 uses the json
parameter inside the initOidcClient function when calling makeOidcConfig(json),
but json is missing from the dependency array at line 63. Add json to the
dependency array alongside oidcClient so that when json changes, the OIDC client
will be re-initialized with the new configuration, ensuring the React hook
contract is followed.
