Hmm, what happens at the next line (if (thumbnail.ToString().Length == 0) return;)? Does it throw an exception or simply return?

[NightRannie]

hello，because the callback sends a request，if the thumbnail is empty I don't want to send it

I see that you're testing the function in the Editor but it isn't supported in the Editor. Please try it on Android or iOS device instead.
