Hi @dmytro.tsytrytskyi. It appears module handling has changed in go. I am updating the application now and will post a new zip file shortly. Thank you for reporting this issue.

spgreenberg

Hi @dmytro.tsytrytskyi . Here is an updated zip file. We will update the class artifact downloads as well. Thank you for pointing out this issue.

Hi @dmytro.tsytrytskyi,

The class artifacts file has been updated in the course as well.

Thank you for flagging this.

@dmytro.tsytrytskyi The manifest does not specify an application path:

---
applications:
- name: training-app
  instances: 1
  memory: 64M
  buildpacks:
  - go_buildpack

Therefore, you are pushing the contents of whatever directory you are in. You need to use the -p flag .Assuming the training-app.zip file is in the same directory:

cf push training-app --random-route -p training-app.zip

dmytro.tsytrytskyi

Thank you. You are absolutely right. I missed this part.
