Notices - Trying to access array offset on value of type null

[rcheesley]

Hi folks!

We are tracking this issue here - it impacts on a few areas of Mautic that I have found in my testing:

Multiple areas of Mautic throw a 500 error

@mohit.aghera has made a PR to address this issue - can you please test it?

Add validation to ensure that we are not trying to access attributes …

Thanks in advance!
