int32 and int64 are not valid format specifiers

[Alan-R]

At least in the statefulspec.json file, {"format": "int32"} and {"format": "int64"} occur many times.

According to the JSON schema specification, these are not legal format types.

They make some JSON schema verifiers reject these specifications - because they aren't valid format specifiers.

You are right.
int32 and int64 are part of the OpenAPI spec and not part of the JSONSchema spec.
But I think you should open this issue in the repo where the script that is doing this conversation is located:
