If you look at gst-inspect-1.0 tee output, you'll find that the
template for tee pads naming is "src_%u", which means it will be in the
format of "src_0", "src_1", etc. When requesting pads, you can simply
pass the template "src_%u" in order to let tee choose a name.

Queue element pad name is just "sink".

Clearly you didn't validate the value of queue_pad1 and tee_pad1.
