doesn't sync - also no creation of daily note

[Sigbert11]

I am also a passionate user of pinboard. wanted to integrate pinboard and obsidian

Now

• have correctly entered all the plugin settings and Api-key (which works fine with other apps)
• a manual initiated sync via the command results in an error message
  • 
• the scheduled sync presumably never happens

I am I missing out on anything?

using

on Mac M1

• Obsidian Version 1.1.8 (Installer 0.15.6)
• with the following settings
