1714645 – NoMethodError: undefined method `[]' for nil:NilClass

Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Lukáš Hellebrandt 2019-05-28 14:03:12 UTC

Description of problem:
When generating a report, sometimes, after getting to Download page, the error "Internal Server Error: the server was unable to finish the request. This may be caused by unavailability of some required service, incorrect API call or a server-side bug. There may be more information in the server's logs." is shown and the report is not generated.
There is "NoMethodError: undefined method `[]' for nil:NilClass" with traceback in production.log (attached).

This only happened to me once and I don't know how to trigger it. The only nonstandard thing in that case was "Generate at" set to past but I couldn't reproduce again this way.

Version-Release number of selected component (if applicable):
Reproduced on Sat 6.6 snap 4.

How reproducible:
Only happened once (in ~ 100 attempts)

Steps to Reproduce:
1. Monitoring -> Report Templates
2. Generate any template
3. Submit

Actual results:
Sometimes, it fails with an error and traceback

Expected results:
This should always work

Moving this bug to POST for triage into Satellite 6 since the upstream issue https://projects.theforeman.org/issues/26942 has been resolved.

I have opened the PR, sorry for the delay :(

Comment 12 Lukáš Hellebrandt 2019-07-16 11:25:33 UTC

Verified sanity-only (since no reproducer) with Sat 6.6 snap 11, generating reports works.
