for me i have remove checkAvailability from node_modules/@ionic-native/contacts/ngx/index.js file line 17.
because it was write two time.

I can confirm Mayank5510's comment. After adjusting the index.js file (rename second, duplicated parameter), everything works as expected.

This is still an issue in the npm package beta-5.0.0-beta.17

[Dineshrajaa]

This issue still persist in ionic-native/contacts-5.0.0-beta.21

Hi, I'm trying to find multiple contacts inside a foreach loop.
When I want to find the 2nd time, the contacts plugin fails with the error "create() failed, expecting Object, String given".
This is the line of the plugin that's failing:
The field "result[i]" has an "OK" string instead of a Contact.
I checked that the problem was related to "system availability", but I don't know how to fix it.
currently running "cordova-plugin-contacts": "^3.0.1" and "@ionic-native/contacts": "^4.15.0",

hello, should we update library directly yet?

[ezequielbarnes]

Hi!, I've just waited a few seconds after trying again.
If you use the Promises correctly, you won't have any problem.
You have to set up a flag that blocks all attempts of using the Contacts
library until the last request has finished (async await it's a really good
way to achieve this)

Hope it helps!

@ezequielbarnes I got same issue.

btw, your problem seems to be that you have the "checkAvailability" import twice. I don't think it's the same problem that I had.

This is still an issue in beta.22 - A revert to beta.15 fixes the problem.
