I want one call to finish before I call the other.

const [certificateKey, certificateCsr] = await acme.crypto.createCsr({ commonName: '*.test.com', altNames: ['test.com'] });

If I do this, I call the challengeCreateFn method at the same time.
I want one call to finish before I call the other.

This is the log:
2022-11-11 01:25:03 Triggered challengeCreateFn() dns-01
2022-11-11 01:25:03 Triggered challengeCreateFn() dns-01
2022-11-11 01:25:03 Triggered challengeRemoveFn() dns-01

and the version:
"acme-client": "^5.0.0"

Because setDns() methods can't run at the same time.

In your code...(auto.js line 87)
const challengePromises = authorizations.map(async (authz) => {
Why do you use "array.map"?
"for(let item of array)" make "await" useful...
Please modify it accordingly, thanks.
