Unable to connect Appium Inspector to session with Bitbar device

Hello, 
I'm trying to connect Appium Inspector to a device on Bitbar, but it always returns an error: "Failed to create session. Request timed out" or "Failed to create session. All non-standard capabilities should have a vendor prefix. The following capabilities did not have one: source".
Am I passing some wrong parameter, or missing something?

Caps:
{
"appium:bitbar_device": "Apple iPhone 12 Pro Max A2411 16.0",
"platformName": "iOS",
"appium:bitbar_app": "201000000",
"appium:bundleId": "br",
"appium:newCommandTimeout": "8000",
"appium:automationName": "XCUITest",
"appium:autoGrantPermissions": "true",
"appium:autoDismissAlerts": "true",
"appium:bitbar_frameworkId": "900",
"appium:bitbar_testTimeout": "8000"
}

  
Can anyone help me?
