Description

I’m using @openapitools/openapi-generator-cli@2.0.3 to generate the code from the openapi spec. Originally, my code worked with 1.0.18-4.3.1 and I was using the command line e.g.

yarn run openapi-generator generate -i /app/schema.json -g typescript-fetch -o /app/output -t /app/templates

After the migration to 2.x I had to modify the command line to

yarn run openapi-generator-cli generate -i /app/schema.json -g typescript-fetch -o /app/output -t /app/templates

and the output for this call is:

I’m behind the corporate firewall and I did not expect to have any calls made by the openapi generator. What are they for and can I turn them off?

This call fails… and I think there is something wrong in the code. I can call the URL from my browser or with curl from terminal. I’m behind a proxy and I think openapi-generator is doing something wrong with the connection.
