I’m stuck on Stage #PV1).
I passed the previous stages, and now when i run my tests with git or codecrafers test
it looks like it tests both the current #PV1 stage and the previous #NC5.
My tests fail because the two stages both require a different reponse (#NC5 only needs message_size, correlation_id and error_code=35, while #PV1 wants a complete ApiVersions Response)
Here are my logs:

Im not pasting in my code because as you can see the newer stage test (#PV1) has already passed, and before that i passed the previous test too, and I assume this is error is not my fault
