Driver failed to start session with message "No matching capabilities found"

[SharpQ]

Hello,
I am using Chromium driver for some time and recently updated it from "1.2.68" to "1.3.15" version.
After driver update, I receive error "session not created: No matching capabilities found" each time on session start.
I didn't change any capabilities from "1.2.68" version and on that version everything works fine.
Could you advise how can I resolve this error and use latest chromium driver version?

MacOS: 11.2.3
Appium Server: 2.2.2
Appium-Python-Client: 3.1.0
Chromium driver: 1.3.15

Driver capabilities:
Creating session with W3C capabilities: {
"alwaysMatch": {
"platformName": "macOS",
"browserName": "chrome",
"appium:automationName": "Chromium",
"appium:autodownloadEnabled": true
},
"firstMatch": [
{}
]
}

I am also attaching Appium log files:
appium_logs.log

try a platformName of 'mac' instead?

Yes, it looks like chrome stricted the platformName to follow w3c webdriver spec chromium/chromium@cac9966
so macOS might be mac

Just checked and it worked. Thanks a lot!
