I am getting the following error when I try to start inspector.
“Failed to create session. The requested resource could not be found, or a request was received using an HTTP method that is not supported by the mapped resource”

“platformName”: “Android”,
“appium:platformVersion”: “11”,
“appium:deviceName”: “Android Emulator”,
“appium:automationName”: “UIAutomator2”,
“appium:app”: “

Version: 2021.9.1

Electron: 13.4.0

Node.js: 14.16.0

I am also getting the same error. Please can some help us

I have the same error with version 1.22.0, but with 1.20.2 version , works fine for me. My phone is a Samsung note 10 plus.

I have the same error:
Failed to create session. Error : Platform can be one of MAC, WIN8, XP, WINDOWS, and ANY

Any ideas?
