Angular does not seem to POST - it seems to use HTTP GET instead, which won’t work with our service.
I don’t know how to make it work, but I suspect it is possible, and I bet someone here may even know. But maybe not any of our staff since we’re currently looking for an Angular expert to fill the gap in our developer experience team, so hopefully another customer will sound off.
But you can see that your code uses GET in the browser developer tools, and hopefully you can figure out how to change that behavior. This post describes this and other requirements of our forms service: [Support Guide] Form problems, form debugging, 404 when submitting
