datamodels warning Error validating header for HDU #0

[stscijgbot-jp]

Issue JP-2062 was created on JIRA by James Davies [X]:

With astropy 4.2.1, we are seeing a bunch of the following warnings in our unit tests:

/Users/jdavies/miniconda3/envs/test/lib/python3.9/site-packages/astropy/io/fits/hdu/hdulist.py:1187: VerifyWarning: Error validating header for HDU #0 (note: Astropy uses zero-based indexing).
      Header size is not multiple of 2880: 188
  There may be extra bytes after the last HDU or the file is corrupted.

To reproduce with a single unit test (there are dozens of others):

Most likely we need to regenerate the test file.

Can't reproduce the problem using the latest astropy and asdf, so I'm closing.

Comment by Howard Bushouse on JIRA:

Just ran these tests (and many more) using asdf=2.9.2 and astropy=5.0 and did not get any of these warnings. So either the test files have already been updated or it's no longer an issue with these later versions of the dependencies. So I'm closing this ticket.
