Power BI Service - Power Query - DataFormat.Error: Invalid cell value '#N/A'

 There are two points to be evaluated:

1. If you want to discard the errors

In this case, just run:

  #"Removed errors" = Table.RemoveRowsWithErrors(StepBefore),

2. Whether to adjust errors due to some columns having value for analysis.

You should select the errors to punctually analyze the non-wrong values and then run the following scripts:  

  #"Kept errors" = Table.SelectRowsWithErrors(StepBefore),

  #"Replaced errors" = Table.ReplaceErrorValues(#"Kept errors", {{[ColumnWithError], null}}),

  

After detecting the column in error, you can delete the Step:  

  #"Kept errors" = Table.SelectRowsWithErrors(StepBefore),

I hope help us!!!
