I am trying to import test steps into Xray from csv.

I map all the fields and choose 'Validate'

Xray tells me there are no issues found.

Yet when I push 'Import Steps', I get an error message 'target test does not exist'.

I cannot figure out what that means. The number in that error message is just the ticket number for the test I am trying to import steps into.
Is anyone able to help me understand what the issue is?
