Better error message for "invalid format"

Windows 10

Version 2024.4.2

Created an environment called 'dev'

added two environment variables one call 'siteone' and another called 'storetwo'

Create a new HTTP Post request

the url is "https:///${[ siteone ]}/${[ storetwo ]}/User/Authenticate"

the body of the request is json and it is the following

{

"userName": "joe",

"password": "12345"

}

when I try making the request I get an error of "invalid format"

But what is the invalid format? I ran my json body through a validator and it checks out, the url interpolation of the environment variables was generated with like the auto complete feature (really nice UX btw).

Like the new tool, and hoping to use it more in the future!
