I built a script to verifying contract source code on block explorers and it is working with BscScan api very well but on the EtherScan and PolygonScan i'm getting this error;
result: "Unable to locate ContractCode at 0x0000.............."
If something wrong with my script it shouldn't work on BscScan too...
What can be wrong?
NOTE: I created seperate API key for all explorers and setted their endpoint URLS, all of them are true.
