hook plugin returns null

hi,

I am using stash 3.6.1 and have a shell script to be triggered as a pre-receive hook via the external hook plugin.

I am getting this message and the push is failing:

Writing objects: 100% (8/8), 670 bytes | 0 bytes/s, done.
Total 8 (delta 6), reused 0 (delta 0)
remote: Hook com.ngs.stash.externalhooks.hook.ExternalPreReceiveHook failed. Error:
remote: null
To ssh://git@<server repo url>:7999/hpln/backend.git
! [remote rejected] BudIceEverGreen -> BudIceEverGreen (pre-receive hook declined)
error: failed to push some refs to 'ssh://git@<server repo url>

 

any idea what is going on ?

That means that the hook com.ngs.stash.externalhooks.hook.ExternalPreReceiveHook is running into an exception and failing as a result. Stash then rejects the request to be safe and not let pushes through that shouldn't be accepted.

Looks like a programming error in the hook,. If I'd have to guess, I'd say it ran into a NullPointerException.

I'd check the logs and raise an issue with the plugin developer that provided that hook. In the mean time, I'd disable the repository hook in the repository settings.

 

you were right, there is an exception in the logs. I hope this is the right place to ask for help, let me know if not.

I've added the addon-com.ngs.stash.externalhooks.external-hoo label to your question to bring it to the attention of the plugin developer

You can also try your luck opening an issue here: https://github.com/ngsru/atlassian-external-hooks/issues

thanks - I will try.
