[iOS] Unable to delete contact

[fpaaske]

I do this:

const response = await NativeScriptContacts.getAllContacts(['name']);
console.log('response.response', response.response);
console.log('response.data', response.data.length);
let first = response.data[0];
console.log('first contact', first);
first.delete();

And I get this error:

ERROR Error: Uncaught (in promise): TypeError: null is not an object (evaluating 'foundContacts.count')

Full output:

This may be related to #77

I'm hitting the same thing in a JavaScript project

I did some debugging, and the code at issue is contact-model.ios.js line 251:

var foundContacts = store.unifiedContactsMatchingPredicateKeysToFetchError(searchPredicate, keysToFetch, null);
if (foundContacts.count > 0) {
    contactRecord = foundContacts[0].mutableCopy();
 }

foundContacts is null, and so foundContacts.count raises an exception.

if (foundContacts && foundContacts.count > 0) {

It's not clear yet why store.unifiedContactsMatchingPredicateKeysToFetchError is returning null.

[edit]

I've been investigating further, as I really need this to work. I tried replacing unifiedContactsMatchingPredicateKeysToFetchError with unifiedContactWithIdentifierKeysToFetchError but with no luck. Both functions take a third parameter which the doc simply describes as, "Error information, if an error occurred." but I haven't found anyway to catch the error data, even within a try/catch block.

If anyone knows how to catch the error data that would certainly help.

[edit 2]

This post looks pertinent. I'll investigate later today.

[edit 3]

Here's what's changed: com.apple.developer.contacts.notes

Apple has made access to the notes field more restricted. If I comment-out "note" from keysToFetch, the contact.delete() works as expected. Next I'll figure out how I want to proceed with this. I don't really need the notes field, and that may mean I'll locally modify my own copy of the plugin to remove it from keysToFetch.

[edit 4]

This issue is a dupe of #89, and fixed with pull request #90.

[edit 5]

Correction: while issue #89 does address a similar issue, pr #90 does not include changes to contact-model.ios.js, and thus does not fix this particular issue. To bypass the issue it is sufficient to comment out line 244 ("note",) in keysToFetch.
