Need help with Todoist plugin in Obsidian

Hello everyone!

I’m facing an issue with the Todoist plugin in Obsidian and could really use some help.

The problem:
When trying to display tasks from Todoist in Obsidian, I get the error:
“The Todoist API has rejected the request. Please check the filter to ensure it is valid.”

What works:

  • The API token is successfully accepted by the plugin (green checkmark in settings)
  • Creating new tasks in Todoist from Obsidian works correctly

What doesn’t work:

  • Tasks from Todoist are not displayed in Obsidian
  • Even a simple inbox filter doesn’t work

Example query:

name: Daily Quests
filter: "Inbox"

What I’ve tried:

Has anyone encountered something similar or has any ideas on how to solve this? Any help would be greatly appreciated!

Thank you in advance for your replies!

I have been experiencing a similar issue with my Todoist Context Bridge plugin. Everything has worked nicely until today. I received this Todoist API error, stating that the task cannot be synced to Todoist.

I’m seeing similar behavior on the Ultimate Todoist Sync plugin today.

I think something changed on the Todoist API endpoint or something (and it started this morning). I get various issues like 404’s trying to retrieve the Todoist favicon, and “Failed to fetch” errors, among others.

I can still retrieve info via another plugin (Todoist Sync) but can’t push new tasks and task status changes to Todoist via the Ultimate Todoist Sync plugin. Hoping it gets resolved / cleared as suddenly as it appeared…
