• What is the cause and solution for SAP error message REST_CORE_TEXTS033 - Matrix parameter are not supported by REST library anymore ?

  The error message "REST_CORE_TEXTS033 Matrix parameter are not supported by REST library anymore" in SAP typically indicates that the REST API you are trying to use does not support matrix parameters. Matrix parameters are often used in URL query strings to pass additional parameters in a structured way, but some RESTful services may not support them due to design choices or limitations.
  Cause:
  
  Deprecated Feature: The REST library you are using may have deprecated support for matrix parameters in favor of a more standard approach to passing parameters, such as query parameters.
  Incorrect API Usage: The API endpoint you are trying to access may not be designed to handle matrix parameters, leading to this error.
  Version Mismatch: If you are using an older version of the API or library, it may not support certain features that newer versions do.
  
  Solution:
  
  Check API Documentation: Review the official API documentation to understand the supported parameters and their formats. Look for examples of how to structure your requests without using matrix parameters.
  Use Query Parameters: Instead of using matrix parameters, switch to using standard query parameters in your API calls. For example, instead of using /resource;param1=value1;param2=value2, use /resource?param1=value1&param2=value2.
  Update Your Code: Modify your code to construct the API requests using the supported parameter format. Ensure that you are following the latest standards and practices as outlined in the documentation.
  Check for Updates: If you are using an older version of the REST library, consider updating to the latest version that may have improved support and features.
