Post Bitbucket App Installation clientKey value changed

Hello Folks,

I currently have a published bitbucket application

Here are details related to the app:

Vendor: Slik Protect
App Name: Slik Code Scanner

Generally once the installation is completed, the redirect_url mentioned as part our installation_url is called with the query parameter of clientKey which contained the workspace_id of the bitbucket workspace where the application was installated.

Since yesterday, we started receiving a different value for the clientKey clientKey=connection%3A5358231

Can you help us understand what that value represents and is there a way for us to get back workspace_id that we used to receive earlier?
