Cannot Select Repository for Chunk

Overview

When setting up the Chunk AI assistant, the repository picker is grayed out and cannot be selected, and the user is unable to select the repository they want to use.

Root Cause

The GitHub App integration is mandatory for Chunk to function. Chunk is only compatible with organizations that use either a full GitHub App integration or a hybrid setup (GitHub OAuth combined with GitHub App). Organizations relying solely on GitHub OAuth are not supported.

Repository selection may not be available if the GitHub App was installed for the wrong organization - for example, if it was set up under a personal account instead of the organization that owns the repositories you're trying to access.
 

Solution

1. Go to your Organization Settings. 
2. Navigate to VCS Connections. 
3. Check whether the connection is a GitHub App integration and which user or organization it belongs to. 
4. If the GitHub App is installed for the wrong organization, install or reinstall it for the correct organization - the one that owns the repositories you want to use with Chunk.
