@abcoathup @Skyge could you please help with above?

Hi @senavi , Does the account that you are calling mint from have the MINTER_ROLE? How are you testing this? Are you able to share the contract?

Thanks @abcoathup , i was able to mint after commenting the sync function … i am using remix … but with sync function still i am getting gas estimation error … even after granting MINT_ROLE to account. Could you please check your same contract in remix once …just to confirm?
