Error 1103 on zenfone

Dear all,
when running my apps on asus zenfone it shows “ERROR 1103”, but run smoothly on vivo
is it because of the phone or because of bugs in kodular ?
please advise
thank you

Can you please show your blocks, specifically the ones where the error occurred?

I use App Inventor Tutorials and Examples: MySQL | Pura Vida Apps for retrieving mysql data
blocks (1)
blocks (2)

only error on certain cell phone
I’m pretty sure the slow internet connection is not the issuer here
because I tried install the apk to 3 cell phone ( vivo, oppo, asus)
only vivo works, all of the cell phone using the same internet connection

the screen.erroroccurred return
componen = “[email protected]
function name= PostText
error number = 1103
message = ERROR
