  Configuration Issues: There may be configuration settings that are not properly set up to handle near-line storage data.
  Query Design: The design of the query may not be optimized for accessing near-line storage data, leading to this error.
  
  Solution:
  
  Review Query Design: Check the design of the query or report that is generating the error. Ensure that it is not attempting to access near-line storage data directly.
  Use Appropriate Data Access Methods: If you need to access data from near-line storage, consider using the appropriate methods or tools that are designed to handle such data. This may involve using specific queries or data models that are optimized for near-line storage.
