I could not get the react app created by the truffle unbox react command to
run. I had to change the react version in package.json to 16.6.3 to get it
to run.
2. The chapter does not say anything about the openZepplin library though
it is required for the application to run. There is no instruction to
install it in this chapter. I used instructions from an earlier chapter.
3. Another issue is the port #. It is not 9545. It is 8545. Also, if and
when you modify a contract and re-migrate it, the changes were not getting
recognized until you shut down and restart the private network created by
the 'truffle develop' command. It occurred to me that i could use the
''--reset' but i never tried it.
4. Finally, the biggest problem i had was with the submit handler. It is
the biggest beucase I spent nearly an hour to figure out why the
setGreeting was not working. Finally, I got it to work by replacing
const updateGreeting = await contract.methods.setGreeting(greeting);
with
const updateGreeting = await contract.methods.setGreeting(greeting).send({
from: accounts[0]});

Chap 5
Chapter 5 |
Hello there,
There are several mistakes in Chapter 5 of "Hands-On Smart Contract Development with Solidity and Ethereum" by Kevin Solorio, Randall Kanna, David H. Hoover.
And I didn't see any fix for this issue on the errata page.
Referencing the online book from oreilly.com at this URL: https://learning.oreilly.com/library/view/hands-on-smart-contract/9781492045250/ch05.html
The book states:
Now let’s copy the client code from Chapter 9 into our Greeter project:
$ cp -r hoscdev/chapter-9/client greeter/client
Unfortunately, there is no "client" directory within the chapter 9 sources. Can you advise on what the correct steps are to setup the project for this chapter?
Also missing are the needed steps to property get the NPM dependencies installed.
While I'm here, instructions prior to the cp command above say to type this:
# go to the directory containing our greeter project
$ cd ..
# clone the repo
$ git clone git@github.com:RedSquirrelTech/hoscdev.git
That git clone command won't work. Correct way to clone the repo is this:
$ git clone https://github.com/RedSquirrelTech/hoscdev.git
Thanks,
jrs

I have been struggling through the first chapters of the book and am finding errors all the time. I can conform all errors of the unconfirmed errata.
I know that Linux developers keep changing everything all the time and this type of book would need to be reviewed at least every 3 months.
Just 2 cents. take care.

Function names |
When listing the mandatory functions for implementation. They are named “setTransfer” instead of “safeTransfer”. A minor mistake really.

Book references Parity client which has since been renamed OpenEthereum
Book uses Goerli testnet which requires download of an enormous amount of blockchain data, enough to overwhelm most users (well over 100GB)
Book uses git references such as chapter-9/client that actually do not exist in Git

Command following 4th paragraph |
When I run the command: $ bash <(curl https://get.parity.io -L) I get a message "Could not resolve host". I think the name of the Parity client has changed to OpenEthereum with a different URL, although I'm not certain here.

Chapter 3: Installing Parity |
The very first command we're told to run to get Parity from get.parity.io doesn't work, because that URL must have changed. Can you please fix this? This is in the Kindle version of the ebook.

$ npm install open zeppelin-solidity
The command fails because project.json is not created by ‘truffle init’. A work-around is to run ‘npm init’ first, and enter the information requested.

./net-pln.sh createChannel command is not working properly |
when I try to run the ./net-pln.sh createChannel command results in channel creation failed and it gives some config type of error and tls error.
I'm being trying to run the Network but all in vain.
