Deployment with capistrano - Rake Task fails

[ck2000]

I am trying to deploy using the asset pipeline. I am receiving the following message:

Tasks: TOP => deploy:assets:precompile (See full trace by running task with --trace) The deploy has failed with an error: Exception while executing as xxxx : rake exit status: 1 rake aborted!

What am I doing wrong? Iam using ruby 2.6.3 and rails 5.2.3

@ck2000 I'm pretty sure we don't have a test case for manifest_name, which is what you are using. I think the OP fixed this in his fork, but I'll need to write a test for this, duplicate the error, and then push the fix.

Okay, please let me know if I can give you a helping hand. Having this fixed in the master branch makes sense.
