Validation error

Python Help
1

Can anyone help me fix this error:

pydantic.error_wrappers.ValidationError: 1 validation error for Lockfile
package -> 390 -> optional
  field required (type=value_error.missing)
2

I have not used pydantic, but it apparently wants a value for some field of a Lockfile instance.

I’m getting the exact same issue when attempting to set up Chipyard (1.4. Initial Repository Setup — Chipyard 1.9.0 documentation). My conda-lock version is 2.0.0. This is my full callstack:

@notooth I was able to fix my issue by downgrading from conda-lock version 2.0.0 to version 1.4.0.
