[zunda]

Steps to reproduce the problem

1. Apply Fix not compacting incoming signed JSON-LD activities #17426
2. Send a GET request to `/users/(account)' with 'Accept: application/json' request header

Expected behaviour

Responded with a JSON data for the account

Actual behaviour

Responded with a 500 Internal Server Error

Specifications

Puma records the error like

method=GET path=/users/zundan format=json controller=AccountsController action=show status=500 error='TypeError: no implicit conversion of nil into Hash' duration=20.80 view=0.00 db=2.88

TypeError (no implicit conversion of nil into Hash):

This seems to be fixed with zunda@52edc13 but I'm not sure if this is the correct way to fix it.

What version of Mastodon does it occur on? It seems like you may have applied the patch incorrectly.

I now understand the error is from me leaving the Keybase proof on my server with reverting #17045. Thanks for pointing that out!
