RetryMiddleware uses CredentialsWrapper scope when invoked

[pkruithof]

The RetryMiddleware triggers a fatal error in some conditions: Call to undefined method Google\ApiCore\CredentialsWrapper::getRetryFunction()

The issue is caused when the middleware is invoked, seemingly with the scope of the CredentialsWrapper, causing the getRetryFunction() method not to be found in the class. I've tried to extract this portion of the client trait into a reproducible script, but that does not trigger the error unfortunately.

Environment details

• OS: Linux (on Docker)
• PHP version: 8.3.7
• Package name and version: google/gax

Steps to reproduce

I cannot reproduce it with a short script, however we occasionally have issues popping up in Sentry about this. I hope this information provides more insights into why this is happening.

I am running into the same issue. Were you able to fix this?

[pkruithof]

Unfortunately not, hopefully someone at Google notices this 🤞

Also having this issue. Does anyone have a workaround?

EDIT: 2024-12-10-0946
I seem to only have this problem when,

• using GRPC
• using Topic::publishBatch
• passing retrySettings in the options parameter to publishBatch

If I use Topic::publish with no additional parameters, it does not happen.
