Patch for deprecated warnings

Hi @rbaer,

Extremekly sorry for the late reply. I read your topic, but missed to reply.

There is no public repository to submit the changes. Could you please list the changes made? I’ll make the same changes and accomodate it in the next release.

Thanks,

Aakash

The changes are to avoid working on non-strings (invalid values).
