Expression.Error: The column " " of the table wasn't found.

Hi

Please does anyone know how to resolve the above. I'm getting Expression.Error: The column " " of the table wasn't found. However, the column is present in my data source and I can also see it in Power query.

Thanks in advance @po

Once your "column name in your table" was re-name, query will error.
You should changed the column name back to origin as it be.
Hope can help you.

Thanks @ShirinArshadnia . I tried that option but it didn't work but I got it at the end by changing th Power Query code from advance editor

Did you find a solution to this issue? What did you edit in the powerquery code in the advanced editor?

Same thing happens to me. No errors on any step in PwerQuery Editor but I get an error when I publish. The column referenced in the error always shows up when it is referenced in different steps.

Hi

I'm so sorry I can't remember exactly what I did. But I hope you are able to resolve it

hi@Adebimpe 

The error message occurs when a column name changes or is removed altogether from the data source. In the background, Power Query is attempting to locate a specific column name that no longer exists.

The quickest solution is to go into the Power Query editor, locate the step that is causing the problem (most likely the "Changed Type" step), and remove the step completely.

please Refresh each table individually.

then "Refresh data".

That should assist.
