[16384] text_styles is deprecated. Fatal error on line 307 in /shared/libs/vendor/google/cloud-document-ai/src/V1/Document.php

[ethan1141]

I encountered a fatal error due to the deprecation of text_styles while working with Google Cloud Document AI on my PHP application.

System Information
Library Version: 2.1.0
PHP Version: PHP 8.3.12 (cli) (built: Sep 27 2024 04:03:16) (NTS)
Environment:Debian GNU/Linux 11 (bullseye)

Steps to Reproduce
Initialize the Google Cloud Document AI library.
im calling

          $documentProcessor = new GoogleDocumentAIProcessor(GoogleDocumentAIProcessors::INVOICE);
          $document = $documentProcessor->processDocument($file->getPath() . "/" . $file->getFileName());
          $documentText = GoogleDocumentAIProcessor::processInvoiceDocument($document);

The following error is displayed:
SYSTEM ERROR - [16384] text_styles is deprecated. Fatal error on line 307 in file /shared/libs/vendor/google/cloud-document-ai/src/V1/Document.php

Expected Behavior
The text_styles deprecation should ideally trigger a deprecation warning without causing a fatal error, or a recommended alternative should be provided.

Actual Behavior
The method triggers a fatal error, halting the application. Additionally, commenting out trigger_error() results in another error:
SYSTEM EXCEPTION - Uncaught Exception: Call to undefined function Google\Protobuf\Internal\bccomp() in /shared/api.myjourneymaker.au-www/libs/vendor/google/protobuf/src/Google/Protobuf/Internal/Message.php on line 939
