Solved the above issue.

But now I am getting this error: No Contract deployed with name NftMarketPlace

I've set the contract name similarly and yet getting this error.

@Shawon-Mandal Make sure your contract name is correct. Also check the deploy file for this contract, it should contain the tag all

@alymurtazamemon
My contract name is correct,And I've checked the deploy file of this contract ,it contains the tag "all"
also,the contract deploys successfully and does not have any other problems with anything else.I just cant test it.
Can you please check the repo mentioned above?I've updated everything there
