I have created custom app and upload to git and followed below step to get my custom app on server and getting error while installing so try to resolved it.

Step 1 : bench get-app [repo-link]
Step 2 : bench --site site1 install-app manufacture

and gives me below traceback error.

Did you check if there is any issue with this module?

@Harsh_Mehta,

Can you access the app when you run bench start and do you have the other apps installed + the latest database?

I also encountered a similar problem when I installed an app from a repository first before restoring the latest database from a parent instance. I didn’t even need to re-install the app. Restoring the database fixed my problem.

Hope this helps. :slight_smile:

Thank you for your reply. I have checked and it’s working smoothly on my local environment.

I have production version installed so no need to do bench start. And I have fresh database till now.

I see. Can you check Installed Apps on your server/production instance and see if the app was installed or not? And if it is, try to see if it runs.

By the way, did bench get-app [repo-link] return any errors? I’ve used bench get-app [app-name] [repo-link] and the docs I’ve seen also follow that command. :slight_smile:
