• If any updated dependencies on Pipfile, also update dependencies in requirements.txt.
• Interactions with external systems are wrapped in try/except
• Error handling exists for unusual or missing values

Validated user-facing changes (if applicable)

• Tag @dotgov-designers in this PR's Reviewers for design review. If code is not user-facing, delete design reviewer checklist
• Verify new pages have been added to .pa11yci file so that they will be tested with our automated accessibility testing
• Checked keyboard navigability
• Tested general usability, landmarks, page header structure, and links with a screen reader (such as Voiceover or ANDI)

As a code reviewer, I have

Reviewed, tested, and left feedback about the changes

• Pulled this branch locally and tested it
• Verified code meets all checks above. Address any checks that are not satisfied

@abroddrick I think we noticed an existing bug here. If UserDomainRole already exists, emails are sent before attempt is made to add a UserDomainRole, and an exception is raised. I think we need to add an additional check here for existing user_domain_roles
