Thank you for the good book. In Ch2 "API Introduction", I've tried to git clone the project repository, and install the dependencies, but I got an error message, as per the following, could you please advise how I can rectify it: C:\projects\notedly>git clone git@github.com:javascripteverywhere/api.git Cloning into 'api'... Warning: Permanently added the RSA host key for IP address '140.82.114.4' to the list of known hosts. git@github.com: Permission denied (publickey). fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. Thanks in advance for your help

first code block

In the version of date-fns as of 05/2021, parseISO needs to be used on the date string. Also it objects to the use of YYYY for the year part. Therefore, {format(note.createdAt, 'MMM Do YYYY')} needs to become: {format(parseISO(note.createdAt), 'MMM do yyyy')}

Various points throughout the "Local State Management"

The version of the Apollo client at 05/2021 not longer supports cache.writedata. The solution I found was to use the Apollo tutorial at https://www.apollographql.com/docs/tutorial/local-state/, which makes use of "makeVar" instead. This needs an extra file to hold the cache definitions and queries, but, then potentially simplifies the other implementation.

NoteForm's Form.onSubmit function

In the current print version, it says ``` onSubmit={e => { [...] props.action({ variables: ...values } }); }} ``` Instead it must be ``` onSubmit={e => { [...] props.action({ variables: ...value } }); }} ``` So value instead of values. In the current version, the code won't work.
