Auto webhook creation broken for Bitbucket 6.x and earlier

Note from project maintainer

This issue still exists for Bitbucket v5.x. Fixing that is tracked in #352. This has been fixed for Bitbucket v6.x in v2.9.1 of the plugin. To enable the fix, you must go to your Bitbucket Endpoint Configuration and set the “Server Version” to “Bitbucket 6.x (and earlier)”.
The credentials being used must also have sufficient permissions to create hooks on the the Bitbucket project.

Description

Jenkins version - 2.22.1 Plugin version - 2.8.0 Bitbucket server and version - 5.4.1

When I perform a ‘Scan Organization Folder Now’, I expect webhooks to be registered for my repos but this does not occur and instead I see 400 errors in the logs.

Could not register hooks for sandbox/wordpress-app

@ssc327 thank you for help.

I’ve tried different combinations last week, before plugin update, but not all today. The permissions setting didn’t help last week so I forgot to check this after updating a plugins. Now I’ve done new tests using Bitbucket Branch Source Plugin 2.9.1

BitBucket Permissions	WebHook Impl	Hook	Jenkins log
write	native	absent	exception (response code = 401)
write	plugin	absent	exception (response code = 401)
admin	native	created	“Registering hook for …”
admin	plugin	created	“Registering hook for …”

@marx-freedom does the account that you are using have permission to make webhooks on the BB project?
