Cannot read properties of undefined (reading 'known')Hello,
I have this problem today on QuantConnect :
Any code I run make this error : “Cannot read properties of undefined (reading 'known')”.
I googled it and it seems to be a problem of JavaScript (the site, not my code).
I tried with my code and the basic template and it's the same.
I also tried using Edge and Firefox, but it shows the same error.
Any idea ?

I had the same issue today, but I found there are two play buttons on the top right now. The smaller back button is to run current file in the interactive window, which leads to the error message. The other bigger one is to backtest project, which is the correct one.

Yes, the yellow play button worked for me.
