AttributeError: 'ImportTask' object has no attribute 'item'

After installing oldestdate plugin and running import I get:

beets version 1.5.0
Python version 3.9.5

Any ideas on how to resolve?

Are you by any chance running the import in album mode? The plugin is made to work with singleton imports

[romleinster]

Yes, I was importing albums. I missed that note in docs, I'll give it a try importing individual tracks. Thank you!

I set

oldestdate:
    auto: no

and this error still happens to me. The only way I can import albums is to remove oldestdate from the plugins list.
