@nicoabie hello nicoabie, good job! Glad you contributed the linear plugin, looking forward to the final product. By the way, is there a corresponding issue for this pr.

@nicoabie Hey Nico, you've gotten the setup correct for testing purposes. All you need to do is follow my comment here to create and save the connection in Devlake, and then run the plugin using the plugin's main method. You will need to know the connectionID to run main(): the PostConnection API will return that to you in the response. Alternatively, you can look it up in the connections table of the Devlake DB.
