I tried installing the Calibre Import plugin (this one - it was introduced in this post) but it doesn't work. I created an issue on their repo, no responses.
To all intent and purposes the plugin is dead, it should be removed from the list for safety (what with abandoned plugins being a potential attack vector for hackers)
Hi, I'm the creator of this plugin. I tried to debug it on my PC. Indeed, it does not work anymore. The reason was:
When I select a Calibre database folder (this is Joplin code), the program execution does not arrive in my plugin code. The framework logs an error : PluginRunner: Could not send IPC message. Error: An object could not be cloned.
The only object in the IPC message is a string with the database folder. I cannot imagine, that the plugin is responsible for this error. Perhaps a member of the Joplin team can have a look at the problem.
