Query string params parsed incorrectly if the URL ends with another param

This may be recorded elsewhere (I couldn’t think of how to search for it) or it may be user error. But when I tried to parameterize a URL like this, where the ending URL part is a parameter, and I want to parameterize some query string bits, it didn’t work as expected:

https://localhost:3399/api/invoice/list/:sourceCode?createdBy=:user

The parameters Yaak recognized were

• sourceCode (expected)
• sourceCode?createdBy=:user (expected “user”)

It doesn’t seem to recognize the break between the ending URL param and any query string.
