Error: This command is deprecated and will be removed in a future release, --legacy flag is required to use it

I observe the following error in the logs when running a test target with Xcode 16

Error: This command is deprecated and will be removed in a future release, --legacy flag is required to use it.
Usage: xcresulttool get object [--legacy] --path <path> [--id <id>] [--version <version>] [--format <format>]
  See 'xcresulttool get object --help' for more information.

The error originates from here

xctestrunner/xctestrunner/test_runner/xcresult_util.py

Line 111 in b7698df

'xcrun', 'xcresulttool', 'get', '--format', 'json', '--path',

I can reproduce the error by manually running

$ xcrun xcresulttool get --format json --path 'path/to/test.xcresult'

Error: This command is deprecated and will be removed in a future release, --legacy flag is required to use it.
Usage: xcresulttool get object [--legacy] --path <path> [--id <id>] [--version <version>] [--format <format>]
  See 'xcresulttool get object --help' for more information.

and the same for xcrun xcresulttool export ...

As the error message suggests, adding --legacy flag resolves the error

$ xcrun xcresulttool get --legacy --format json --path '/Users/vakhid.betrakhmadov/Downloads/outputs/test.xcresult'

{
  "_type" : {
    "_name" : "ActionsInvocationRecord"
  },
  ...
}
