Phantom.debug() string won't perform string interpolation.

[nhammSplunk]

Why won't this phantom.debug() string perform string interpolation?

foo = "bar"
phantom.debug("Testing: {foo}")

It should read as "Testing: bar"

This is an old question but I believe it is because you forgot the f before the string.
It should be:

phantom.debug(f"Testing: {foo}")

This method works for that:

phantom.debug("Testing: {}".format(foo))
