How do I make a call to the setName() function of this simple contract from web3? I am able to make a call to the getName() function from web3 and receive the correct value in console. I just don't know how to call setter methods from web3. Kindly help. Thanks! :)

These ^ are some of the things I've tried so far. Nothing seems to work :(

Try with then instead of callbacks function

Tried. Doesn't work..

Do one thing
Before calling setName , log userAddress

I have hardcoded userAddress above the code in the screenshot. It shouldn't be any issue. Console logging userAddress works just fine.

Show me error

Try this:
1. Add Contract ABI to ja File
2. Add contract address to file
3. call function directly from the contract

As for example shown here:

Yes, I've tried this as well. Doing this didn't result in any error, but it made the program stuck forever. I first thought that the transaction is taking time, but nothing happened for a long time so I just had to Ctrl+C. Not sure what the problem was..

Problem is that this Call uses gas

You somehow need to confirm the transaction

If you call this function in a browser with metamask, fo example, metamask will pop up and wants you to confirm

„Problem“ == difference (between the two functions)

exactly show us error so that we can help u accordingly

i think for testing string is okay, it looks like he is learning so

for real life usage bytes should be preferred, it's cost efficient

i also prefer async and await over then

This is the error I was getting on running this code:
