Fileid not defined

"Failed to generate request url from template: https://zuora.com/apps/api/batch-query/file/{{data.fileId}}. Details: \"fileId\" not defined in the model. - 1:46."

We are getting the above error and I do not know what it means or how to fix it. It implies that something is expected (fileid) but it is not defined or present. I checked the error information and fileid is not listed. We now have this error 32 times.

I will confess that I am new to this. The person who used to do this is no longer with the company.

Please contact customer support to get help. This is a very simple issue to fix, but it requires seeing your flow, data, etc... and it is probably not a good idea to share this type info in the community.
