Request failed with status code 400 (trySwap) 1Inch plugin in ethereum boilerplate

Technical Issue Reporting
#2

Kindly help?
I’m not getting proper error response object if balance is insufficient etc.

#3

What is the code that you use for swap?

#4

Using exact code that is available at Moralis’s ethereum-boilerplate for swapping tokens. If you need me to share exact snippet, then let me know.

#5

You can share a snippet, I’m not familiar with that code. There is also a specific forum thread for ethereum boilerplate questions.

const { Moralis, account } = useMoralis();

    if (!Moralis?.["Plugins"]?.["oneInch"]) return null;

It’s the Moralis component’s named useInchDex which is responsable for dex functionality. I don’t have much experience with Moralis package. But it’s not giving me proper error handling i.e. for insufficient balance etc when swapping tokens

#8

Do you have latest version of 1Inch plugin? Not sure if it matters?

#9

Yes, I’ve it installed

can you also paste that payload?
it should be a response somewhere too, even if it is an error

The error is telling you that you don’t have enought native tokens to swap.

"Not enough 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Amount: 1000000000000000000. Balance: 0.

Indeed 0xd6ab7b48a4637b3d7977b62773d481c47d09eadc seems to have 0 BNB

#16

I understand that, but I’m not getting proper json response!? why is that? Seems like proper error handling at the backend is missing? I could be wrong though!

#17

See, I’ve to show the exact error string on the frontend in any case what so ever which I should get from the backend no?

#18

you need to fill you wallet with some NFT first man :raised_hands: then the error will disappear when you swap~

#19

Oh I see! Alright let me do that
