Upload a testcase bug - ERROR: 'NoneType' object has no attribute 'filename'

[sfiecko]

Hi!

As ClusterFuzz discovers a testcase I want to check if the other version is vulnerable as well. Sadly, when following a path Testcases -> testcase-detail/testcase_id -> Re-upload Testcase -> I'm unable to pass the testcase to other version. Error occurs (screenshot below). What is more curious, it is not happening with all of the testcases, so it is kind of a lottery.

Details of this testcase: Parameters passed with the POST: upload-testcase?upload=true&gestures=%5B%5D&job=libfuzzer_asan_linux_libwasm&target=FuzzLibwasm_v1&testcaseId=5751860518453248 Error message:

Thank you in advance!

Hi there, sorry for the slow reply.

Is this on a production deployment, or local instance?

This occurred only on production deployment. Local instance was working fine 😄
