I got an error while Bluemix was deploying a python flask project

Question

I added bootstrap .css and .js files into my project in GitHub. At Bluemix, the build process is successfully done, but the deploy is not. I got an error, and here are the deploying process logs:

Thanks for your help.

Answer 1

Problem may be related to hardcoded port number . Your log shows that server is listening on 5000.

When you are running your application on Bluemix, you can't request for a specific port . You have to use the port assigned for your application by the platform.

Please review : Flask code sample [1]

Port is defined here : [2]
