[corneliusroemer]

Came here to open this! I'm encountering the issue when testing in bioconda. My conda-build version: 24.5.1

I've modified the code that errors to workaround the issue. Replace line 332 with:

                                    if type(v) == str:
                                      values[k] = v
                                    else:
                                      values[k] = v.copy()

I've also found out what the root cause is by printing:
