Error "Cannot read property 'exists' of Null" when adding a new action on an already existing Flow

Hi all

I have an already existing Flow, just some minutes ago I opened it to add a new action block, but I can't since Flow editor is showing the following error:

FlowCannotReadPropertyExistsOfNull.png

 

It's a bit difficult for me to share screenshots of the flow logic since it is a bit complex (more than 10 action blocks, 2 conditions, 1 foreach); if you find it valuable I can export it and share the .zip file instead

 

Thank you in advance!

Re: Error "Cannot read property 'exists' of Null" when adding a new action on an already e

I have the same issue.  I'm trying to add new actions to my flow and it keeps telling me "Cannot read property 'exists" of null".

 

I tried to save my flow and restart, but it isn't going away. Any other ideas?

Hi @Anonymous, @efialttes and @ch2017

 

I did a lot of tests and discover that the problem is a cache - simple press CTRL + SHIFT + R and it workarounds the problem.

 

We are waiting for a fix

Hi all,

 

Apologize for the current situation.

This is a known issue, and a fix is being published this week.

 

Edit:

To workaround this, please take a try to refresh the current editing page, which should be able to get the Add new Action work.

 

Regards,

Michael

I hope this is resolves sooner rather than later as it's hard to finish a flow when you cannot edit it. Guess the customer just have to be patient.
