This error indicates that a text type field in your OData service is being sent with an initial (empty) value, which is not allowed.

  Mapping Issues: There could be issues in the mapping between the backend data model and the OData service, leading to empty values being sent.
  
  Solution:
  
  Check Data Population: Ensure that the text type fields are being populated correctly in your backend logic before the OData service is called. This may involve checking the data retrieval logic or the data being sent to the OData service.
  Modify OData Service: If certain fields are optional, consider modifying the OData service definition to allow for null or empty values if that aligns with your business logic.
  Validation Logic: Implement validation logic in your backend code to ensure that required fields are populated before the OData service is invoked.
  Debugging: Use debugging tools to trace the data flow and identify where the empty value is being introduced. This can help pinpoint the exact location in the code where the issue arises.
  Check Annotations: Review the annotations in your OData service metadata to ensure that the fields are correctly defined as required or optional based on your business requirements.
