1727988 - browserAction.setIcon() throws "IconPath not found" error

Status: RESOLVED DUPLICATE of bug 1725144

(Thunderbird :: Add-Ons: Extensions API, defect)

Description

[r-a-y]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

This is a simplified version of the code I'm using to change the button icon when a button is clicked:

browser.browserAction.onClicked.addListener(() => {
const icon = 'icons/heart-outline.svg'

browser.browserAction.setIcon({ path: { '16': icon, '32': icon } })
})

Note that "icon" is a relative path.

Actual results:

In v78, when I clicked on my browserAction button, my button would also change its icon.

In v91, I get the following error:

13:13:21.008 Error: Internal error: Type IconPath not found Schemas.jsm:1602:13

Expected results:

In v91, the button icon should change as it did in previous versions.

It doesn't appear that browserAction.setIcon has changed since v78.
