Server error on jobs.lookup_jid with runner client

[bbinet]

When I run a function asynchronously with --client=local_async, I can't get the result with jobs.lookup_jid runner because it generates a HTTP Error 500: Internal Server Error.

For example:

$ pepper --client=local_async test-mc-1 test.ping
jid:
    20200701073413349464
minions:
    - test-mc-1

$ pepper -vvv --client=runner jobs.lookup_jid jid=20200701073413349464

    raise HTTPError(req.full_url, code, msg, hdrs, fp)

Pepper error: Server error.

FYI, the issue is the same with pepper v0.7.6 and develop branch and salt-master version 2019.2.4 (Fluorine).

Are you able to reproduce this issue ?

Also I can't see any relevant issue in salt-master and salt-api logs.

there seems to be an issue with kwarg to arg spec parsing in salt itself. in the interim you can change the jid= to just a [jid], I need to look into salt siide when/where this broke.
