Issue with src-dest-check

[JPaineCap]

When running the cross-az module, the below errors are produced.

The source-dest-check is defined in the ENI, but the error is in the aws_instance block which makes this weird.

Can you suggest a solution...? Copilot suggests the module maintainers need to fix something but I am not sure if this is a provider issue instead (provider assumes one ENI per instance?).

Please advise.
