Given following log snippets, their explanation, and nothing else, explain what failure, if any, occurred during build of this package.

  Snippets are in a format of [X] : [Y], where [X] is a log snippet, and [Y] is the explanation.

  Snippets are delimited with '================'.

  Drawing on information from all snippets, provide a concise explanation of the issue and recommend a solution.

  Explanation of the issue, and recommended solution, should take a handful of sentences.

  Snippets:

  [1 out of 1 hunk FAILED -- saving rejects to file tests/unit/customizations/cloudtrail/test_validation.py.rej
]: [This is the output of the patch command. It indicates that it failed.]
=============
[error: Bad exit status from /var/tmp/rpm-tmp.3GevrQ (%prep)]: [This is a line from rpmbuild that indicates that the build failed during %prep section execution.]

Issue: The build failed because (at least) one of the patches failed to be applied.
Resolution: It is necessary to examine the patch that failed to apply and fix it - in this case the changes have been already applied upstream so the patch could be simply removed.
