I updated my server with PHP 7.4.2 and now I am getting this :
~/public_html/infusionsoft$ php composer.phar update [ErrorException] Trying to access array offset on value of type null
I had to revert back to 7.3.14 and it works. But is composer not PHP 7.4 ready ?
This is a composer issue and has been fixed in this release:
In order to fix this issue please update your composer.
