Hi All,

Trying to install koa.1 and koa.2 releases and both are currently failing to installs. Below is the error log. Not sure if anyone else also facing similar issue.

Any pointers will be helpful.

Hi @Gaurav_Vijayvergia,

We’ve done some testing around the new koa.2a tag yesterday, and none of us ran into this particular issue. Did you follow the native installation instructions? If so, did you do anything different? Any settings that are different from the default, perhaps?

Hi @arbrandes ,

Following the same steps mentioned on native install. This is my config.yml . Not sure if any of the variable might cause this issue.

Have you tried simply not setting this variable?

Hi @arbrandes ,

Yes i already tried that. Finally manage to fix the installation issue. This property causes the actual issue. After removing it , the installation was successful.

EDXAPP_FEATURES_DEFAULT:
   ENABLE_OAUTH2_PROVIDER: true
   CUSTOM_COURSES_EDX: true

Thanks & Regards
