This error indicates that the operation you are trying to perform is expected to return a single entity, but the response is either empty or contains multiple entities.
  Causes:
  
  Incorrect OData Service Configuration: The OData service might be incorrectly configured to return multiple entities when a single entity is expected.
  Query Parameters: The request might be formulated in such a way that it inadvertently requests multiple records instead of a single one.
  Data Issues: The underlying data might not conform to the expected structure, leading to unexpected results.

  Check the OData Service Definition: Ensure that the service is defined to return a single entity. Review the service metadata and ensure that the entity set is correctly defined.
  Review the Request: Check the request being sent to the OData service. Ensure that it is correctly formatted to request a single entity. For example, if you are using an ID to fetch a specific record, ensure that the ID is correct and that it corresponds to a single entity.
  Debug the Service Implementation: If you have access to the backend implementation of the OData service, debug the code to see how the request is being processed. Look for any logic that might be causing it to return multiple entities.
  Check for Filters: If you are using filters in your request, ensure that they are correctly applied to narrow down the results to a single entity.
  Review the Data: Check the underlying data in the database to ensure that there are no duplicates or issues that might cause multiple records to be returned.
