Customer CSV Error - Unable to find a matching line for sublist contactroles with key: [contact].

edited Nov 4, 2025 1:52PM in Ask A Guru 3 comments

I'm getting the error 'Unable to find a matching line for sublist contactroles with key: [contact].' and I'm not really sure what it means. I know these errors can usually be really misleading so I thought I would ask here.

Here is my mapping

Here is my CSV

Here is the response

All I'm trying to do is update 3 customer records to have this contact. The password value is different on each, so that shouldn't be the issue.

TEV2079 actually already has this contact on their customer record, so if the issue were that I would expect the result for them to be different from the other two.
