In order for us to put this into the OJS app store, we need to have tests written such as the tests of this OJS plugin in github actions: https://github.com/leibniz-psychology/openid/blob/master/.github/workflows/openid_plugin_test.yml.

See guidelines for app store release here: https://docs.pkp.sfu.ca/dev/plugin-guide/en/release

With OJS 3.1.2.4, the NotificationManager throws the fatal error below in the communication between Fiduswriter and OJS. It seems that the ContextId (= journalId) is transmitted as string instead as integer as probably requested by OJS (see third line of code).

On OJS 3.1.2.4, opening the settings of OJS-Fiduswriter 1.3.1.0 throws the error Failed Ajax request or invalid JSON returned.
The obviously related PHP warnings are given below. Similar error messages are reported from other OJS-plugins, so the issue seems related to the construction of paths:
ajnyga/embedGalley#6

Considering that OJS is already at 3.2, are there any tests available if the current plugin-version is compatible to 3.2?

During submission via Fiduswriter to OJS, two rows are added to the backend-MySQL-table "submission_settings" that handle the communication between FW and OJS. It appears that in the row for the address of the FW-server, the URL erroneously starts with "http:". This leads to an error 500 when clicking on the Fiduswriter-link in OJS. If changed manually to "https:", everything works as expected. The error might also originate in the fiduswriter-ojs-plugin.
