Sharing Lambda between distributions results in incorrect redirects

I'm trying to use this lambda on two different Cloudfront distributions, with 2 different corresponding OIDC configs.

However it looks like either something is being cached or possibly I'm hitting a container reuse issue?

How can I work-around this issue?

Start by tracing the Lambda's redirect handling when it is attached to two CloudFront distributions with different OIDC configurations. Reproduce the behavior with both distributions and verify that each redirect uses its corresponding configuration; document the confirmed workaround or corrected behavior.
