Looper - pephub is broken

[nsheff]

When I run the hello world example on how to use looper with PEPhub, I get this error:

looper run
Looper version: 1.7.0
Command: run
Using looper config (.looper.yaml).
Traceback (most recent call last):

I am wondering if this is related to:

• change in the API URL

Either way, we need to

1. fix the problem
2. make this error message more clear about what is happening, in case this happens again in the future. As in, if it's something like the server is not working, it should say "couldn't connect to the server" or if the API appears to no longer be compatible, it could say "couldn't get record from PEPhub API at URL: https://xyz... "

I think this issue is outdated, you should use pephubclient version >0.3.0

updating to pephubclient 0.4.0 and the error went away. thanks.

probably should change this: https://github.com/pepkit/looper/blob/1468956dde66abf5b853c80eaeaee2d411bfad64/requirements/requirements-all.txt#L7
