1. Indesign CC 2020 (15.0.2)

2. 2- version) From Object menu:

   "Select insert HTML.."

   "This is an HTML snippet."

I paste the codes into HTML box, a second later, small box message,

 "JavaScript Error encountered while loading HTML"

Even this message comes when Im not changing the default text.

I have tried Indesign 2019 (14.0) abd the same error message comes.
