Raraible clone 7 NFT minting errors

hi there, so i have been following the amazing tutorial on how to clone a marketplace like rarible and so far am enjoying it. however i recently came across which was not allowing me to mint an NFT, and was getting an error saying that create item is not defined.

i tried looking for errors in the code and couldn’t find any. so i decided to continue the tutorial coding wile searched for an answer, however i didn’t go far and after reaching part 9 everything stop working and now i get a new error. before everything else was working such as login, save, logout, etc except create item were i mint the NFT, but no everything is completely not working and just a "uncaught SyntaxError: Malformed arrow function parameter list in Main.js line 168 ".

i believe this error is caused by the code not being able to point to any nft since i couldnt mint before.
would really appreacite any help. thank you.
