None that I found

Suggest a fix

Will dive into templates and latest master release on a less busy day.

Reproduce the report with the supplied OpenAPI schema, then run npm install and npm run build to inspect the generated models and the missing URI.ts import. Trace the TypeScript generator's handling of string properties with format: uri. Done means the generated output includes the required URI type and the TypeScript build completes without TS2307 errors.
