The path '/oauth/token' was not found

I'm trying to get an answer from the oauth address, but when I call to:

https://podio.com/oauth/token?grant_type=password&username=$username&password=$password&client_id=MY_APP_ID&redirect_uri=http://localhost/dashboard&client_secret=MY_APP_SECRET

I get an error:

"error_description": "No matching operation could be found. The path '\/oauth\/token' was not found..",

$username is my email

$password is my password

MY_APP_ID is the users app id

MY_APP_SECRET is the users app secret

But even when I do not use a body in the request of https://podio.com/oauth/token I get as an answer that The path '\/oauth\/token' was not found.

I tried the same with https://api.podio.com/oauth/token and https://api.podio.com:443/oauth/token urls but same result of no '/oauth/token' path has been found...

I tried it from insomnia, also directly from the browser and from a symfony app I'm developing. Always same result.

Is the documentation outdated? I see in the documentation that I have to make a POST to /oauth/token : https://developers.podio.com/doc/oauth-authorization/get-access-token-22359

But when I try it I see no matching operation could be found with that path...
