What is the `polyGeometry`?
Can you try to generate a compilable, minimal, self-contained example that demonstrates the problem?

ERROR 6: No translation for an empty SRS to PROJ.4 format is known. I think, this occurs, because I could not assign any SRS value to polygon How can I solve this problem? regards -- Ahmet Temiz Jeoloji Müh.
