As a site-admin, when I use the feature Suggest changes I got the error Something went wrong

Summary

There are cases where admins using the "Suggest changes" feature are presented with the error "Something went wrong".

Steps to Reproduce

1. Go to https://instance.atlassian.net/admin/users
2. Click "Show details" next to the user you want to suggest changes
3. Click "Suggest changes"
4. Type a new name
5. Click Suggest changes

Expected Results

It should send an email to the user with the new name that was suggested

Actual Results

The message "Something went wrong" is displayed

Notes

The feature sends a single payload with both suggested name and email, and if you fail to type an email, the error will occur with a 400 status.

{"key":"fieldConstraintsViolated","context":{"fieldViolations":[{"field":"suggestChangeDetails.arg1.email.value","violations":[{"key":"Value is not a valid email address"}]}]}}

Workaround

In case you want to suggest just a name change, type also the same email.
