Hi there, 👋🏼

please excuse me if this has already been mentioned, but I did not find it.
I have a problem with building an API client using the openAPI Rust client generator.
I am building an application in Rust that is supposed to automate the onboarding and update processes when dealing with machines. To do that I need an API client. As I would like to not implement it by hand I tried using the generator to build a Rust crate for me. With the 3.6 spec that my companie's internal instance is using this seems to work (or at least it generates code). However, when trying to do the same thing for the public test instance which I use as a reference, I get this error:

~/ sudo npx @openapitools/openapi-generator-cli generate -i public_netbox_schema_3.7.yaml -g rust -o public_client_v3.7/

Download 7.2.0 ...
Downloaded 7.2.0
Did set selected version to 7.2.0

oh, this would be unfortunate, completely missed this 👀
I'll check if I can find some reference for a limit like this with the generator, thanks!
