Internal server error when trying to use official Shared Edits plugin

[mxmilkiib]

Describe the bug

When I enable the Shared Edits and then try to use it, I get an Internal Server Error

https://meta.discourse.org/t/enable-shared-edits-gives-internal-server-error-message/266281/3

Context

• Hardware: VPS
• YunoHost version: 11.1.20
• I have access to my server: SSH
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: No. nothing but install some plugins, using the YunoHost instructions for installing Discourse plugins

P.S. is there not a ./launcher available, like apparently with the default Discourse install?
