This typically occurs when you are trying to use a property that has a conversion defined (like a custom data type or a specific format) along with a pattern that is not supported by the OData service.
  Cause:

  Solution:
  
  Check Property Definitions: Review the property definitions in your OData model. Ensure that the properties that are using conversions do not also have patterns that are incompatible.
  Adjust Annotations: If you are using annotations to define patterns or conversions, ensure that they are correctly defined and compatible with each other.
  Remove Incompatible Patterns: If a property is defined with a conversion, consider removing any patterns that are not supported or necessary.
  Update OData Service: If you have made changes to the model, ensure that you regenerate the OData service and update the metadata accordingly.
