Error on adding "Reviewer Suggested by Author" - Submission inaccessible

[Anil]

Describe the issue or problem
We are encountering the error message “Call to a member function getData() on null.” when attempting to add an “Reviewer suggested by Author” from the Add reviewer screen in editor role. As a result, the submission becomes inaccessible to both the author and the admin users.

Steps I took leading up to the issue
For example:

1. Go to ‘From the Editor Dashboard - Goto Submission -
   Scroll down to the reviewer area - Click Add Reviewer - New Screen appears wtih Add Reviewer - Goto “Select Reviewer from Reviewer Suggestion - “Select Reviewer” - Fill the details and Click on “Add Reviewer”
   Nothing happens upon clicking Add Reviewer.
2. If you click anywhere on the screen after this, the following error message appears: “Call to a member function getData() on null.”
3. The submission then becomes inaccessible to both the author and adminusers

What application are you using?
Current version: 3.5.0.1
