Hi @jbistis, this sounds like an issue caused by your linter. Can you share what linter you're using (e.g. ESLint) and if you have applied any specific rules (e.g. 'consistent-return')? Thanks

Yes, thanks. The update was to set "noImplicitReturns": false per https://stackoverflow.com/questions/51446242/how-to-fix-the-issue-not-all-the-code-paths-return-value
