Fusion
I am not able to understand the problem you are noticing. If possible please share script so We can take a look and try to reproduce the problem on our side. Thanks.

Hello,
First, read the explanations by @marshaltu here: Can't get Javascript add-in to communicate with palette
Next, do not create the palette inside the run function. See there : [bug] Palette created in the run function and Run on Startup enabled
Last, please use the button </> to insert code in your message.

Can you share the complete add-in (Python & HTML files) ?

Ah cool! thank you, so I have to create new thread for that.
Yes. You can't use sendInfoToHTML inside MyHTMLEventHandler.
That's what @marshaltu explained (see the link I provided in my first reply).
