Error handling deep link: Invalid text for prompt

Support Bug Reports
1

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I’m encountering an error when using sharing deep links / web links, even when the prompt is well under the 8,000-character limit.

For reference, this example link (https://dub.sh/5nADDgz) contains only 4,391 characters and also works correctly in the website playground: Deeplinks | Cursor Docs

Given that the prompt is within the documented character limit, it’s unclear what is causing the deep link to fail.

Steps to Reproduce

Visit https://dub.sh/5nADDgz to see the deeplink and open it in cursor. It will say error handling deep link: invalid text for prompt

Expected Behavior

The deeplink is valid and should work.

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. This is a known issue with URL parsing in deeplinks. It’s already been reported and the team is aware.

Also, looks like you reported the same thing about a month ago: Parsing issues with Deeplinks

The issue is in how Cursor decodes URL parameters. Some valid prompts are incorrectly marked as invalid. The team is working on a fix, but there’s no ETA yet.
