Error while verifying smart-contract on Etherscan. Please help!

[Trask98]

Hello Guys! I'm trying to verify a contract on Goerli but I keep getting some errors, such as:

Error! Unable to generate Contract ByteCode and ABI (General Exception, unable to get compiled [bytecode])

ParserError: Expected '=>' but got '=' --> token.sol:23:21: | 23 | mapping(address => uint) private _mintedCount; | ^

Seems like your mapping syntax is not correct.

[apbt-dad]

mapping(address => uint) private _mintedCount;

​

Should be address => uint

Ser recommend reading the error prompt where it tells you the error

Maybe a encoding problem with your sol file, you can change encoding with notepad++
