Invalid provider - only instances of Provider and Type are allowed, got: [object Object]


I recreated the project using a blank template. Creating the pages, services, models etc and copying over the code from the previous project. I have added in the dependancies as far as I can see. I have uploaded to ionic view. Running the ionic serve has an issue. Is this something obvious to fix?

Thanks for your help - Ben

The error suggests you have an improper provider declared somewhere. Look where providers are declared. I would start with the app module.

Its a very simple app. I can not see anything obvious in the declarations and this compiled before in an earlier incarnation of ionic 2. Thank you for your suggestion. - Ben

Yeah, but beta5 was a really long time ago. Quite possible that Angular and even Typescript were different back then. Look at the providers, maybe missing an annotation or something?

Yes I agree. I imported the browser and http modules into app component with the providers and the splash screen + bar native for Ionic 3x. I will spend some times going through it line by line. Cheers - When I have the solution I will post - cheers

@Bendeverell did you came up with something? :slight_smile:

Hi Lucy

I’ve been side tracked for a few days. I will look at it early next week. Shouldn’t be too difficult. Will post what I needed to change to make it work


Ok, looking forward… I have removed all my code… only basic structure of ionic app remained and still getting the error :smile:

Even I got the same error after removing all the code.
