Cloud function retuning array of PFObject, can not be cast in iOS (Swift)

[skotadia]

I am returning PFObjects from cloud function(s) and in my app (iOS SDK), I am using Subclassing. However, it gives error:

fatal error: NSArray element failed to match the Swift Array Element type

It works fine with api.parse.com but not with my local parse-server. Thanks

Sounds strange - any chance you can try to print out that array? It might be coming back as array of dictionaries instead of array of Parse Objects / Pointers - that's the only reason that comes to my mind.

I haven't print them out, At least in XCode debugger, it was showing NSDirectory. I will confirm it if there is difference between them.

I have the same problem, I think is because the result is missing "__type" and "className"

[laullon]

I thin this can be related to parse JS lib, ParseObject.js have 2 methods:

• _toFullJSON , this one add the "__type" and "className"
• toJSON , this one don't....

and the express framework is using "toJSON"

[nlutsenko]

Yup - it needs the __type notation to be able to recognize that it's a full object.

[laullon]

I'm trying to use a "json replacer" function to use _toFullJSON function, or to add the both properties, bu, no luck so far...

Any recommendation?

[skotadia]

I am not hands on with nodejs (that was the reason, I started with Parse), Anyone has any idea or work around to continue my migration? At this point I have stuck. Thanks a lot.

[laullon]

I opened a bug on the Parse-SDK-JS, I think the problem is there.

parse-community/Parse-SDK-JS#199

[laullon]

I know how to solve this when I return this:
response.success(np);

But no if I return something like this:
response.success({ photo : np });
or any other object that contains a ParseObject.

any idea?

[laullon]

I did solve it...
PR: #252

German: Thanks a lot. I just tested out and it works like a charm. Do you know when is it going to be in master branch?

[nlutsenko]

Just merged it, already on master ;)
