@decentralized-86 Make sure that not any of them is undefined by consoling this array args.

[haseebmalikk]

Thats work for ma.Thanks brother

[CHYGO1985]

@decentralized-86 if still error occurs then do not forget to leave a link of your GitHub repo

I had the same issue, and this resolves mine:) thx

[teerth17]

@decentralized-86 if still error occurs then do not forget to leave a link of your GitHub repo

Hi @alymurtazamemon I am getting the exact same error and my order of args is the same as in the constructor. please help

[alymurtazamemon]

@teerth17 Hey! please create a separate discussion and post your query there and tag me also.

[mikechaban]

This helped me. Thank you, @alymurtazamemon

[othaime-en]

Hey @decentralized-86 you are defining the subscriptionId twice using const please rewrite you code appropriately. Remove the const in all subscriptionId and add subscriptionId in the line let vrfCoordinatorv2address;. Like this let vrfCoordinatorv2address, subscriptionId;

[othaime-en]

Hey @decentralized-86 the error has changed. The error is now on the callbackGasLimit variable. Please share your helper-hardhat-config.js file. I want to look into it.

To make this more efficient, also push your code to github and leave a link here.

@othaime-en hey man,just followed your twitter but your dm is locked, follow back please,there is a dapp project i wanna collab on

[othaime-en]

Hey @decentralized-86 in your lottery.sol code, change uint16 callbackGasLimit in the constructor to uint32 callbackGasLimit You are getting this error because the callbackGasLimit value you are passing (500000) is way above what uint16 can accomodate (65535)
Tell me if it fixes your issue.

much obliged

I had this bug as well with a different solution. I needed to update the code that gets the subscriptionId to subscriptionId = transactionReceipt.events[0].args.subId

[Glow-in-the-dark]

What did u do to solve it ? any additional details ?

nah couldn't solve it the issue still persist

I have tried all of the above solutions but still, the error persists, can anyone suggest a solution?
