[Maakai123]

I got the below error when deploying my Raffle contract to rinkeby network

Error: invalid BigNumber value (argument="value", value=undefined, code=INVALID_ARGUMENT, version=bignumber/5.6.2)

@Maakai123 I saw this issue

- subscriptionId = networkConfig[chainId]["subscription"]
+ subscriptionId = networkConfig[chainId]["subscriptionId"]

[krakxn]

Did you module.export it properly in the verify script?

[alymurtazamemon]

@Maakai123 There could be other issues as well it would be better to push to GitHub and leave a link here so we can find all issues at once.

[Maakai123]

@alymurtazamemon mistakenly deleted my repo after i ran into issues, i changed some files i wanted modify them then i made a MISTAKE, i deleted my repo thinking i could create a new one..

i will start from afresh thank you so much

[alymurtazamemon]

@Maakai123 Ok so should I close this?

[Maakai123]

yes let me start again, thanks

transactionReceipt.events[0].args.subId
This code is the root cause of this issue. It returns a bigNumber so just convert it into a String.
Like this - (transactionReceipt.events[0].args.subId).toString()

Only Change the code that is inside your IF statement.
