Not able to launch Safari browser, getting error "SessionNotCreatedError: Request body does not contain required parameter 'capabilities'."

[mkrish03]

I am trying to run my script in Safari 13.0.1 version using uiveri5, I am getting SessionNotCreatedError: Request body does not contain required parameter 'capabilities' when executing the scripts.

capabilities in conf.js browsers: [{ browserName: 'safari', capabilities: { safariOptions: { setTechnologyPreview: true, addArguments:['--legacy'] } } }]

console: uiveri5 --config.browsers[0].browserName=safari --config.browsers[0].capabilities.safariOptions.setTechnologyPreview=true --config.browsers[0].capabilities.safariOptions.addArguments[0]=--legacy INFO: @ui5/uiveri5 v1.40.0 INFO: Resolving specs INFO: Executing 1 specs (node:34864) [DEP0022] DeprecationWarning: os.tmpDir() is deprecated.

Hi, I did some investigation and it seems the problem is somehow bigger, this is the synopsis: https://github.com/SeleniumHQ/selenium/issues/6431#issuecomment-477408650 Unfortunatelly it won't be so easy to switch to selenium 4 as they removed the control flow and this would mean a total rewrite of the tests to use async/await and this causes a totally new set of problems altogether. Please give me some time to research what is the difference between webdriver an w3c protocol and if we can somehow overcome it.
