cannot open xlsx file in mobile mode.

[JoeLucky]

Hello, I new a xlsx file and put some art words to it. (No idea if it is the reason.) And view it on onlyoffice as mobile mode (Using chrome debugging tool). It shows below, loading with no end and show some error.

The file:

I try to find out the reason, but it seems too complex to me.
Thanks for your help.

I add retrun at the abnormal, it can solve the problem, but I am not sure it will cause other problems or not.

Appreciate for your help.
