Error message received: **Cannot read properties of undefined (reading ‘forEach’)
**
Could not open any of my flows for editing
Neither from Hub
Nor from History (/view Run)
Also I tried to build a flow automatically with Gumloop AI (from scratch), resulted in the same error message.
Hey @lacikiszely_AbilityMatrix! If you’re reporting an issue with a flow or an error in a run, please include the run link and make sure it’s shareable so we can take a look.
-
Find your run link on the history page. Format: https://www.gumloop.com/pipeline?run_id={{your_run_id}}&workbook_id={{workbook_id}}
-
Make it shareable by clicking “Share” → ‘Anyone with the link can view’ in the top-left corner of the flow screen.

-
Provide details about the issue—more context helps us troubleshoot faster.
You can find your run history here: https://www.gumloop.com/history
Hey @lacikiszely_AbilityMatrix – Thank you for flagging, can you share the workflow link please?
Literally any flow I select from the hub (or history), eg.: Gumloop | Automation Builder
Same if I try to create a new one
Can you clear cookies and try again now @lacikiszely_AbilityMatrix please? The workflow you shared works for me now.
Cleared cookies, signed out and signed in… Does not work.
The flows themselves work (can be triggered). But I can not open the flows, they lead to a blank “creat new” page with the aforementioned error message.
I was getting the same error “Cannot read properties of undefined (reading ‘forEach’)” attempting to open flows. Cleared cookies and restarted browser no luck. Switched from safari to chrome and it opened.
Thanks for the tip! I am on Chrome though (and I see my personal account is still available on another Chrome, so really strange)
Update: Now I tried with “Edge”, same problem, same error message.
@lacikiszely_AbilityMatrix – Can you try again now please, the issue should be fixed!
Yep, thanks, now they are back for editing and creating, a relief 
No problem! Sorry about the trouble!
This error has popped back up for me. Same use case as before, and same as lacikiszely_AbilityMatrix. Literally any flow I select from the hub (or history)
Cannot read properties of undefined (reading 'forEach')
@TonySnark Can you try again now please? Broader fix for this going out tonight!
