Passing empty string return error with directive <ng-embed>

[fabiancarlos]

ionic.bundle.js:25642 TypeError: $filter(...)(...).$$unwrapTrustedValue is not a function

i have the need to put some string like "." with a dot.

Maybe the best way is to return a empty!

If i put a undefined value return to me:

ionic.bundle.js:25642 TypeError: Cannot read property 'replace' of undefined

I think this is not natural on Javascript way, because can break the rest of the application.
