Compass - The app is not installed on this instance

Question

Hi,

I'm trying to build my own compass app, which runs a custom query from Jira in backend code and send the formatted result to frontend. Frontend maps that data in Compass.

I have tested it in local, querying part is working without any issues. But when I deploy and install the app in Compass I'm getting an issue saying

403 : The app is not installed on this instance

I can see my app in Compass apps, and it's showing as installed. Additionally I can see the app in Compass component menu, even the frontend text. But when I print backend response in console I'm getting this error.

Please can someone help on this? Thanks in advance

Hi @Enrique Serrano Valle

Thank you for the reply.

I have given permission for these scopes

scopes:- read:component:compass- write:component:compass- read:jira-work- read:jira-user- read:issue:jira- read:project:jira

What I'm trying to do is I got a custom JQL, and execute it with

const jql = `custom_jql`;const response = await api.asApp().requestJira(                 route`/rest/api/3/search?          jql=${encodeURIComponent(jql)}&expand=changelog`);

If you got any ideas please let me know, I'll raise it with Forge community as well, thanks

Hi, @Nethanjana Alahapperuma !

The `403: The app is not installed on this instance` error message is a bit cryptic. It's typically received when you are attempting to make a call and your app doesn't have enough permissions to do so.

I suspect this relates to the custom query that you're trying to execute from your Compass app to Jira.

Have you registered your app with the appropriate scopes to perform this call?

(If that didn't solve it, the Forge community may be a better place to get more detailed support about this since it isn't strictly Compass-related. I can see some similar threads in the past suggesting something relatively similar, like this one.)
