ChannelCredentials.php missing?

[verbme...@gmail.com]

Working with PHP client lib & MAMP on an M1 Macbook Pro, followed all the startup steps, confirmed that grpc and protobuf extensions are installed and running, composer installed the cloned git repo...

All seems to have worked correctly, but then trying to make a simple search ($googleAdsServiceClient->search) results in a "Warning: include(ChannelCredentials.php): Failed to open stream: No such file or directory"...

Anyone have any insight?

Actually I've tracked this a bit, and it happens (though silently) even when using one of the built-in example files.

Steps to reproduce:

1) open file google-ads-php/vendor/grpc/grpc/src/lib/BaseStub.php

2) place a breakpoint on line 47

3) open file google-ads-php/examples/Reporting/GetKeywordStats.php

4) for testing purposes, insert valid customer ID on line 42

5) run the GetKeywordStats.php file with a debugger enabled

6) once it hits your breakpoint on line 47 of BaseStub.php, step into the code

7) notice that the code attempts to find and load ChannelCredentials.php, but fails to do so

8) notice also that a call to ChannelCredentials on line 53 does nothing, as the class previously failed to load

Subsequent requests seem to complete successfully, so is this something I should just ignore? And if not, how can I configure my system to actually find ChannelCredentials.php?

Hi,

I'm also from Google Ads API Team. Allow me to provide support here.

Upon checking the information and details mentioned on this thread, I can see that the issue is more specific to the client library rather than Google Ads API. However, I would suggest you reach out to the author of the PHP client library to confirm your clarification as his issue is more specific to the client library. You can reach out to them via the PHP issues tracker on github to get further assistance here as they are more equipped to this concern.

Best regards,

Hi. I had the same problem (PHP 7.4) and I realized that the error is from the "method_exists" function of google-ads-php/vendor/grpc/grpc/src/lib/BaseStub.php.

I solved it by adding the namespace in the string "ChannelCredentials".
Old: method_exists('ChannelCredentials', 'isDefaultRootsPemSet')
New: method_exists('Grpc\ChannelCredentials', 'isDefaultRootsPemSet')

Line 46, probably.

Hope this helps,

Hi Fernanda,

Thank you for sharing your solutions.

As mentioned by our colleague Jinky, and if you wish to further discuss PHP client library specific topics, then this Github channel should be more appropriate as you may also be able to acquire inputs from the client library owners themselves. 

For any Google Ads API services or features concerns, feel free to create a new thread in our forum so our team can further assist you.

Best regards,

Peter Laurence Google Ads API Team
