Getting error using unedited contract from the wizard

[jefedeoro]

Hi
I am trying to deploy a contract from the OpenZeppelin Wizard.
I downloaded the zip and then today unzipped it and loaded it into remix.

I am getting the following error when trying to compile it.

TypeError: Contract "gToken" should be marked as abstract.
--> gToken.sol:13:1:

13 | contract gToken is Initializable, E ... VotesUpgradeable, UUPSUpgradeable {

Environment

Remix on Windows10 64, OpenZeppelin wizard, deploying to Matic Mumbai.

Any and all help is appreciated.
Have a good day.

Hi, welcome!

I am not sure how did you use the UUPS pattern, but I just had a try, and it re-write the function _authorizeUpgrade, and there is also a comment for this function The {_authorizeUpgrade} function must be overridden to include access restriction to the upgrade mechanism

I can't reproduce this. Selecting the same features, _authorizeUpgrade is included in the output. Are you sure you didn't edit the code?
