Put object in a array and Firebase

Im trying to put a list of strings from firebase and just display on the screen… But i’m stuck with this error
Appreciate any tips…Im stuck 2 days now… Thanks
the error say: Error trying to diff ‘[object Object]’

HTML .TS and on bottom is the firebase provider…

I think that the problem is in the return statement in the function getData(). It should be:

return this.http.get(’…’)
.map((resp)=> resp.json())

nop… same error continues

What line is throwing that error?

If it is the *ngFor thingie, you probably need an array and not an object in ‘textos’.
