B4J Question "JSON Array expected" Error when Load layout

universengo · Jul 31, 2019

Hello experts!
Today I continue to have errors about JSON but I don't know how to fix it. May the experts help me.
The error occurred when I loaded the layout.

B4X:

Main.MainForm.RootPane.LoadLayout("frmDangNhap")

See log below:

B4X:
