Problem at the DAY21-ERC20 Token lesson of the DAPP30 training

Hello Everyone,

I hope you are all well.
I have a problem with the frontend.
When I want to use the transferFrom function I get this message:

I provide Ethereum addresses so I don’t understand why it does not work.

Would you have any idea on how tosolve the problem please?

Thank you

Takre care
