Hey @eugenioghio, I've reported this to our Dashboard team to investigate. Is this error continuing on your runs? Or was this error only present on this single run - and has since been passing? Thanks!

Hi @jennifer-shehane , as a matter of facts this error is recurring over and over on all runs.
It happened after I updated cypress.
I will rollback and report here if is this still a thing on older version.

We have identical issue since yesterday morning GMT, still evaluating dashboard.
The issue is showing up on all tests, dashboard needs to be stopped manually.
It appeared on cypress 4.10 but persists after upgrade to 4.12.

@speedwellsoftware Thanks for reporting. This issue may be isolated to Windows as it seems to be occurring in all Windows OS's so far.

Our engineering team has released a fix for this issue - of seeing the Cannot find unclaimed instance for spec error when running in Windows OS's.
Please comment here or open a new issue if you continue to see this issue on new runs that are recorded to the Dashboard.

Hi Jennifer, We are also experiencing same issue when ran tests "Cannot find unclaimed instance for spec " locally or on Azure DevOps pipeline, it gets worst when used it along with -parallel flag which suppresses original issue (Cannot find unclaimed instance for spec )
I've seen your comments on engineering team has released a fix but there is no information on changelog on a release will it be possible to tell when can we get a new bug fix
?

on 13 Aug 2020
@amargourishetty This was a fix made by our API team. When you record tests to our Dashboard - this makes API requests - the original bug was in introduced around 2 days ago on one of those requests, so that fix went out immediately without requiring an update to a new Cypress version.
All new runs made after the comment above should no longer have this issue. If you are seeing this error on new runs after that time, please run cypress run in debug mode mode and print the entire set of logs here.

Our engineering team has released a fix for this issue - of seeing the Cannot find unclaimed instance for spec error when running in Windows OS's. This fix should be immediate and not require a new version of Cypress.
Please comment here or open a new issue if you continue to see this issue on any new runs that are recorded to the Dashboard.
