Issue :
An error occurred on the workflow instance Import audiences from the Adobe Experience Cloud (importSharedAudience) while processing the task Load IDs and segments (fileImport) .
Error: Too many columns :
To resolve this issue, review the segment data, there are multiple segment IDs with comma-separated values.
There should be one segment ID for each Operator ID. When the data extraction is performed, IT uses a comma (Sometimes space as well) as the separator and 1 comma means 2 columns. There is no issue on camping’s end.
The issue is with the Customer id as it has an extra space in it, to resolve this issue fix the extra spaces.
