Tried to convert your openapi.yaml to TypeScript SDK, and failed due to type assertion. The type assertion error message was ``info.license.urlis not following theuriformat, and found that the property value was a little bit weird. Theurl` value must be trimmed without any space.

This PR fixes the spaced url value, so that would be succeeded to convert to the TypeScript SDK like below.
