Ignored key without a value. {"ignoredError": "json: unsupported type: zap.optionFunc"}

DPANIC  crdt    v2@v2.0.7/log.go:44     Ignored key without a value.  {"ignoredError": "json: unsupported type: zap.optionFunc"}

When upgrading to v2.0.7 this happens all over the place in go-ds-crdt tests.

They have a custom logger implementation that wraps this logger: https://github.com/ipfs/go-ds-crdt/blob/master/crdt_test.go#L43

I think the formatting is conflicting with some structured log format that zap is expecting, but I have to look deeper.

Still: The log.go:44 line does not make sense to me, as this would mean the issue is on the logger creation? I am not sure if this means v2.0.7 will break other things, therefore opening this for tracking. If deemed to be go-ds-crdt specific, this can be closed.

Because I didn't read the docs and zap isn't doing eager error checking...
