Hi,

We are experiencing occasional (not always, but frequent) errors when our PWA starts. The screenshot below shows them.

Any idea why?

Sorry guys. I found the error. My mistake. I deleted a couple of variables but I forgot to delete a couple of workflow actions that changed the value of those deleted variables. Everything is working well now.
