Question Umuly File Short URL error in postman

[iveusername]

I get a "400 Bad Request" error in postman when I try to create a file short URL which is served by umuly.com. Here is the error:
{
"status": 400,
"statusText": "Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')",
"item": null,
"itemCount": 0,
"skipCount": 0,
"requestDate": "2020-09-15T04:37:01.4442344-07:00",
"responseDate": "2020-09-15T04:37:01.4827526-07:00"
}
I need help. What can cause this?

HTTP 400 series errors are all server side errors. Contact umuly and let them know. There is nothing you can do from your side.
