Unexpectedly received this error message

[niyonx]

Hi, I use firestore to send documents.

I unexpectedly received

Error: Undefined constant Google\Protobuf\Internal\GPBType::STRING in /firestore/vendor/google/cloud-firestore/src/V1/Document.php:199

and I cannot reproduce it, does anyone know the problem?

Here is the full stack trace

It seems like your project is not correctly autoloading class GPBType from the package google/protobuf. I would recommend verifying that class exists in your vendor directory.

This is a very core class to protobuf, so I do not believe this to be an error on our end. However, if you can provide more information on the issue we can verify that's the case. A few things you can do to debug:

• Run composer info google/protobuf to see what version you have
• Remove the vendor directory and run composer install to reinstall it
• What version of PHP are you using? Which version of this library?
