I've added more logging around claim.go:170: coreClaim, err := schemaPkg.Process(ctx, c.loaderFactory(req.Schema), credentialType, vc, opts)

time=2023-09-01T03:59:23.476Z level=ERROR msg="error parsing claim" err="error parsing claim"
For memory, this is the schema I'm using: https://schema-builder.polygonid.me/schemas/83938bc0-d1f2-49d1-b09f-abfcb85a0c4f
And I'm using "TH" as the country.
I've noted that
CredentialSubject:map[country:TH id:did:polygonid:polygon:mumbai:2qNpRLUS1wXAsXxpQtcW6QFQdkP6KMDjWWvvryaXpe type:country]
contains a "type:country" attribute that I wasn't expecting because it's not in the schema (which contains only "id" and "country" attributes.
I don't know if it's significant.
Adding some logging around schema.go:117: claim, err := pr.ParseClaim(ctx, credential, credentialType, schema, options)
logs the following:

time=2023-09-01T04:27:25.242Z level=INFO msg=err !BADKEY="protected term redefinition: invalid JSON-LD syntax; tried to redefine a protected term"
So the error is actually protected term redefinition: invalid JSON-LD syntax; tried to redefine a protected term and it's hidden behind a generic "can't parse claim".
I don't know where to go from there.
It appears that the parseClaim function returns this error:
time=2023-09-01T12:05:33.995Z level=INFO msg="claim parsing error" err="multiple parents found"
I'll submit a pull request to log this error instead of just wrapping it in a "cannot parse claim" error.
