vcswatch - how to fix Error: fatal: missing blob object '...'

[Julian Gilbey <jdg@debian.org>]

Hi!

I think I've broken vcswatch :(

I was updating jupyter-server-mathjax, but probably messed up a commit
along the line.  Anyway, somehow, vcswatch now says:

Error: fatal: missing blob object 'ae757feb8182c5c3d2934dee63504ea0a87f02ac' error: remote did not send all necessary objects

I checked in my local repository, and the object did once exist (as
discovered by git filter-repo --analyze).  So I did a Repository
cleanup on salsa to ensure that things were clean, and this commit was
not included in the commit-map.

But it still exists in the results of git filter-repo --analyze, and
vscwatch is still making the same complaint.

I have no idea how to fix this - if it is even possible to - any
suggestions would be very welcome!

Best wishes,

   Julian
