Drupal

Updating Drupal from 8.7.10 to 8.8.x or 8.9.x has seen a significant change as it has now moved into 9.x.  It has integrated more with composer, and you can be caught by fatal errors occurring during the update process.  One of these errors for me was the php version.  

When you are in the status report of the admin area are you finding the following issue:

While I have posted an article about how to POST an image using REST in Drupal 8... the journey there can be slow.  Crawling through the errors to eventually spot the missing link.  For me the how to is as important as the solution.

If you are like me you probably have searched for clues to and found little... particularly when confronted by the errors as you unravel how this works.  Okay a slight exaggeration, there are snipets of info that people have solved this annoying issue in  making comments work in Drupal 8 REST services.

For others that have spent countless hours getting this to work and are struggling... in particular assigning the correct user to the comment - this is how I achieved the correct outcome.

The outline below is for usage via Postman and DHC (Restlec Client)... once working here then testing done and ready to apply to your app or however you are using this.

Set accept to hal+json
