{"message":"'toLowerCase' is not a function","name":"TypeError"} with getTransactionCount

[mongodillo]

Hi,

i'm trying to write a simple function within a webhook, and everything is working fine except the nonce for the tx object.

if i manually specify a nonce, the transaction goes through.

But once I start using either provider.getTransactionCount(address) or signer.getTransactionCount() , i am faced with the following error

{"message":"'toLowerCase' is not a function","name":"TypeError"}

I have also tried provider.getTransactionCount(address.toLowerCase()) but no use.

Any advice please?

my provider and signer defns as follows:

const provider = new ethers.providers.JsonRpcProvider(API_URL); //using alchemy api
const walletPrivateKey = new ethers.Wallet(PRIVATE_KEY);
const signer = await walletPrivateKey.connect(ethprovider)

I note that the other functions using provider and signer (such as sendTransaction etc) work fine.

I think I answered a similar question. If that's not the same, can you try logging the address variable?

[mongodillo]

oops yes the same qns

Where's the question that got answered?

[zemse]

I was not sure, otherwise would have linked the issue # here. Anyway ir issues at both places were that address was not a string probably, that's why .toLowerCase would be undefined, and hence JS would throw that toLowerCase is not a function. If you're getting this error please check the inputs.
