The "Unavailable input" error in the LinkedIn Post Commenter and Liker Scraper Workflow means the Workflow can't access or recognize the URL you provided: either because it's broken, unsupported, or was edited after the Workflow started. To fix it: confirm the URL is valid and accessible, make sure the format is supported by this Workflow, replace it if needed, and avoid editing the input once the Workflow is running.
Why you're seeing this
The "Unavailable input" error appears when the Workflow can't access or recognize the URL provided in the input.
It usually means the input link is either not valid, not accessible, or not supported for this specific Workflow.
It can happen for a few reasons:
- The input URL is incorrect or broken.
- The URL isn't supported by this Workflow.
- The input was modified after the Workflow started.
How to fix it
- Confirm the input URL is correct and accessible (not broken or restricted).
- Make sure the URL format is supported by this Workflow.
- Replace the input with a supported URL (if the current one isn't recognized).
- Don't change the input after the Workflow starts (input edits can trigger this error).
Frequently asked questions
What causes the "Unavailable input" error?
The Workflow can't access the URL you gave it, usually because the link is broken, points to an unsupported page type, or was modified after the Workflow started running.
Which URL formats does the LinkedIn Post Commenter and Liker Scraper accept?
A direct URL to a LinkedIn post (a single post, not a feed, profile, or article page). Make sure the post is publicly accessible.
Can I edit the input after my Workflow has started?
No. Editing the input after the Workflow is launched will trigger the "Unavailable input" error. Stop the Workflow, update the input, and relaunch.
Why does my URL work in a browser but not in the Workflow?
The URL may redirect, require login, or point to content that isn't a supported post type. Copy the URL directly from the post (not from your feed or search results).
