There's a build error it seems:

Error: src/message-registry.ts(139,3): error TS2352: Conversion of type '{ options: { syntax: string; }; nested: { ground: { nested: { v1beta1: { options: { java_multiple_files: boolean; java_package: string; }; nested: { AuditInfo: { fields: { userId: { type: string; id: number; }; ... 4 more ...; emailAddress: { ...; }; }; }; ... 13 more ...; Role: { ...; }; }; }; }; }; google: { ...; ...' to type 'MessageRegistryJson' may be a mistake because neither type sufficiently overlaps with the other. If this was intentional, convert the expression to 'unknown' first.
  Types of property 'options' are incompatible.
    Type '{ syntax: string; }' is missing the following properties from type 'ProtoOptions': java_package, java_multiple_files
