Cannot get transaction's field "From"

Question

Cannot get transaction's field "From"

opened this issue 6 years ago · comments

https://github.com/miguelmota/ethereum-development-with-go-book/blob/master/code/transactions.go - this code don't show transaction's field "From".

For instance, for transaction https://etherscan.io/tx/0x5d49fcaa394c97ec8a9c3e7bd9e8388d420fb050a52083ca52ff24b3b65bc9c2 it shows nothing.

For transaction https://etherscan.io/tx/0x36368eb4665367100bcb46427e8ac39b7873abfca2015116c478f84642a8812d it shows 0x0000000000000000000000000000000000000000

Hi @invisible73, the example code shows how to read the transactions FROM address. Take a look below:

Transaction hash (orange) and transaction FROM (red)

Hope this helps. Please reopen issue if you have more questions

Yes, I understand that. Problem is that here is no "from" value in result.

What I have as result:

@invisible73 thanks for the fix! the error was that I had err != nil instead of err == nil
