This error indicates that there are ambiguities in the definition of the InfoProvider, which can lead to issues when trying to access or query the data.
  Cause:
  
  
  Ambiguous Field Names: The most common cause of this error is that there are fields in the InfoProvider that have the same name but come from different sources or tables. This can create confusion for the system when trying to resolve which field to use.
  
  
  Multiple Data Sources: If the InfoProvider is based on multiple data sources, and those sources have overlapping field names, it can lead to ambiguities.
