Batch Run Command sometimes show this error "[kantu] No tab for dashboard yet"


I use firefox ESR 60 portable edition with windows 7, in the past I used firefox 66 portable edition but I had a lot of problems with Kantu.

I start macros with a batch file from the command line and sometimes it shows me this error and the macro does not start, what does it depend on?

Macros work perfectly, this error appears randomly, I don’t understand what generates it and how to avoid it appearing.

I repeat the macro works fine and is started with a batch file that works great, sometimes this error does, NOT always appear, but usually batch file it opens firefox, opens kantu and the macro starts, I would like to know what this error that occurs occasionally.

I see in the forum that even other users occasionally this error appears so there will be a reason.
