Getting this error: datasource.error: the table has no visible columns and cannot be queried.

Hello community,

I am currently working on extracting data from our MongoDB database and have encountered an issue that I would like to discuss.

The problem I am facing is related to one specific collection within the database. When attempting to query this collection, I receive the following error message: "datasource.error: the table has no visible columns and cannot be queried."

To provide some context, here is a sample of the data I obtained when exporting this collection from MongoDB:




What is weird is that the error message suggests that there are no visible columns in the collection, but as you can see, the data contains several columns with meaningful values.

I have attempted various solutions to resolve this issue, including renaming the collection, resetting the database, and even creating a new collection. However, I consistently encounter the same error. Even when creating a new dashboard, the problem persists.

The data types used in this collection include ObjectId, String (x2), Date (x2), and Int32. Could the use of these data types be a contributing factor to the issue?

I have diligently searched for information regarding this specific error related to MongoDB but have not found any relevant insights or solutions.

I would greatly appreciate any guidance or assistance you can provide in resolving this matter. Your expertise and support in addressing this challenge would be invaluable.

Thank you for your time and assistance.

Hi @alozano93 ,

This error might be caused by one of the following reasons:

  • The data source connection is not configured properly. You might need to check your credentials, server name, database name, and port number in the Data source settings.
  • The collection schema is not compatible with Power BI. You might need to modify the schema or use a different connector to access your data.
  • The collection contains nested or complex data types that Power BI cannot handle.

To troubleshoot this issue, you can try the following steps:

  • Refresh the data source and make sure it is up to date.
  • Use the MongoDB Connector for BI instead of the ODBC connector. This connector can handle more complex data types and schemas.
  • Use the Power Query Editor to preview and shape your data. You can apply filters, transformations, and aggregations to your data before loading it into Power BI.

Hi @v-rongtiep-msft, Thanks for your support.

  • The data source connection is not the issue, I’m working with 20 other collections from the database and using the same connection.
  • It doesn’t have nested/complex data types, other collections have them and it doesn’t seem like an issue.
  • The data is up to date.
  • I’m using MongoDB Atlas SQL.
  • Cannot get to Power Query Editor with that one:



  • If I use any other collection, no problem:



apache spark - Querying tables with Power BI returns the "The table has no visible columns"... : In this case, spark issue.

Any other insight will be appreciated.
