Additional context

[larsoner]

I have this same bug. With some inspection I find:

> /home/larsoner/python/virtualenvs/base/lib/python3.11/site-packages/grayskull/license/discovery.py(129)get_short_license_id()
-> recipe_license = match_license(name)
(Pdb) p name
'GPLv3'

So hopefully this makes it easier to replicate!

[marcelotrevisani]

which version of fastbencode did you use to generate the recipe?
Because it seems to work fine for me, it generated fine for 0.2

I will try @larsoner suggestion, thanks! :)

[marcelotrevisani]

can you try to update rapidfuzz to version 3.6.0 please?

[marcelotrevisani]

ah ok, on main that is fixed, I believe I forgot to generate a new release with this fix, I am generating version 2.5.2 that fixes it.
Fixed with
#507

I am closing this issue, if you think that is not fixed with 2.5.2 please let me know and I will take another look, thanks for reporting it :)
