Exception when saving for UWP (Hololens)

[Scano]

Hi Joel,

I'm building an app for the hololens and I ran into the following problem when trying to save a string:

This is the error I receive:

Code: Select all

AggregateException: One or more errors occurred. (The parameter is incorrect.

   at UnityEngine.EventSystems.ExecuteEvents.Execute(IPointerClickHandler handler, BaseEventData eventData)
   at UnityEngine.EventSystems.ExecuteEvents.Execute[T](GameObject target, BaseEventData eventData, EventFunction`1 functor) 

The code I execute is basic:

Code: Select all

    public void Save()
    {
        ES2.Save(myInputField.text, "myText");
    }

A couple of notes:
- The above code worked fine until a couple of weeks ago. I really have no idea why it's not working
- I updated to the latest version of Easy save
- I can't build for the hololens if I have the easy save 3 folder in Plugins (I just delete it)
- I use the holotoolkit (it shouldn't be an issue)
- The scene is really simple: InputField + couple of buttons and a keyboard!

So the question is:
Do you have any idea on what could be causing it, and what I could try?

Hi there,

I've not seen this error before. Please could you try something for me?

Please could you specify the filename in your ES2.Save call. i.e.

ES2.Save(myInputField.text, "myFile.txt?tag=myText");

The only thing I can think is happening is that UWP is recognising the tag as the filename for some reason.

Also with regards to Easy Save 3 not building, please could you send me any errors which are sent to console when you try to build for it?

All the best,
Joel

Thanks for the quick reply:
Unfortunately I already tried your suggestion and it gives the exact same error At this point I believe it has more to do with my device than Easy save. I probably will do a reset and if the error still persists I will let you know.

Concerning ES3, here are the errors:

Code: Select all

Assets\Plugins\Easy Save 3\Scripts\Web\ES3Cloud.cs(696,40): error CS0117: 'TimeZoneInfo' does not contain a definition for 'ConvertTimeToUtc'

Assets\Plugins\Easy Save 3\Scripts\ES3Reflection.cs(395,57): error CS1061: 'IEnumerable<Attribute>' does not contain a definition for 'Length' and no extension method 'Length' accepting a first argument of type 'IEnumerable<Attribute>' could be found (are you missing a using directive or an assembly reference?)

Assets\Plugins\Easy Save 3\Scripts\ES3Reflection.cs(400,71): error CS1061: 'IEnumerable<Attribute>' does not contain a definition for 'Length' and no extension method 'Length' accepting a first argument of type 'IEnumerable<Attribute>' could be found (are you missing a using directive or an assembly reference?)

Assets\Plugins\Easy Save 3\Scripts\ES3Reflection.cs(405,30): error CS1061: 'TypeInfo' does not contain a definition for 'GetInterface' and no extension method 'GetInterface' accepting a first argument of type 'TypeInfo' could be found (are you missing a using directive or an assembly reference?)

BTW If you solve those errors, please let me know I would be glad to use ES3

Hi there,

It looks like some UWP errors from a previous version have crept in from a previous version. If you PM me your invoice number, I'll send you over an update which should get ES3 working for you.

All the best,
Joel

Just a quick update:
I reset to factory settings the hololens and I still had the errors shown above, it's strange because ES2 always worked perfectly. Anyways thanks to the updated package for ES3 now I can use it and it works perfectly fine.

Thanks again for the assistance!

[Joel]

Thanks for the update.

I'll see if anyone else encounters this issue so I have a bit more data to work with. If this is indeed affecting other people, we might move Easy Save 2 away from IsolatedStorage and over to Easy Save 3's method of storage (persistentDataPath).

All the best,
Joel
