Hey @neetu-sharma, looks like you may have a Solidity error as that error is coming from the Solidity compiler. Can you check your code for syntax errors? Also, if you want to link to your project on GitHub I'll happily take a look to see if I can spot an error.

It looks like most likely they're trying to redeclare an identifier that was already declared in an import.
