i am getting below error please help me with that and i am using the above js codeCapture

#2

That error is directly from the contract. For what parameters do you get that error?

#3

Customs taking function
Parameters address amount

#4

Ok, so this one should be. Did you call approve before that?

This function should transfer an erc20 token for stake?

It could also fail on any other check that the function does in the contract.

#5

Yaa approve is working fine

#6

Doublecheck all your executeFunction parameters. It looks like customStaking does not take an address parameter, it only takes _amount.

You can post your contract code also, it may be an issue with the code.

#7

Yes it takes 1 parameter but from where it should it take address

#8

I got the result thanks bro
