Getting 500 error "Java heap space" when testing API on Docs page Create Checkout

I am using the API test on the https://docs.clover.com/reference/createcheckout# page. When I click the "Try it!" button, it returns below json.
Is the server broken?

Just use postman or curl. The doc page is probably building the request wrong. I agree the server should certainly not be throwing an oom. Someone from clover needs to look at this

I just ran it through docs and postman and did not run into any issues. Can you try again?

},
"message": "COS get merchant failed with exception: 401 Unauthorized: [{\"message\":\"401 Unauthorized\"}]"

I added merchant permissions to my private API token. It works now.

I assume refreshing the page, making sure all the required parameters had data, and setting the correct permissions did the trick.
