Got the following error today after updating pangolin and all its dependencies

Had the same issue.
Quick workaround:

If you update pangolin from github and use conda, you might be stuck with an usable pangolin, unless you downgrade scorpio:
in the pangolin source directory edit the line in environment.yml that specifies scorpio like this:

    - git+https://github.com/cov-lineages/scorpio.git@v0.3.1

update the conda environment like this:

conda env update -f environment.yml

Bother - I'd tested it on all the pango-designations sequences, but must not have triggered this clause. I'll put in a fix

rmcolq commented

Given how bad broken pangolin is, I've created a new release that should theoretically fix this. If either of you is able to check that would be awesome as I've not been able to replicate the issue here - or provide an example which should definitely break it?

Hi Rachel, here is a file that breaks it:
sequences.fa.zip

mcroxen commented

@rmcolq still broken

pangolin already latest release (v3.1.4)
pangolearn already latest release (2021-06-15)
constellations already latest release (v0.0.9)
scorpio already latest release (v0.3.3)
pango-designation already latest release (v1.2.22)
rmcolq commented

I've tried again - I think this must be OS/biopython version specific as the example worked fine for me - any better?

I'm on biopython v1.79 and macOS. But I think the fixes I made in v0.3.4 worked

Confirming the changes to scorpio (v0.3.4) have eliminated the bug.
The sequences file provided above was for triggering the error with scorpio v0.3.2
