Steps to Test or Reproduce

Extract the workspace from reproduce.tar.gz

# generate the OpenApi schema
> python3 gen.py

# generate Typescript using orval
> npx orval

# Make a copy of the output
> cp gen/reproduce.ts gen/reproduce-one.ts

# Rerun the generator
> npx orval

# diff the two outputs
> diff gen/reproduce-one.ts gen/reproduce.ts

The two output files should be identical.
