Hi,

This sounds like a bug in the keyword you use. I don't know that
keyword, you didn't even tell thich library you use, so possibly you
are using it somehow wrong, but even in that case you should get a
better error message. To find out where in the keyword code the error
occurs, you can run tests with `--loglevel debug` that enables showing
failure tracebacks in the log file. If you don't then understand
what's going on, you need to contact the author of the library you are
using.

Cheers,
.peke

Hi,

Based on the traceback the `banner` variable is `None` but I don't
know why that happens. You should submit an issue about this to
SSHLibrary's issue tracker. if possible, include an example that can
be used to demonstrate the problem in the report.
