Unitywebrequest Exception Data Processing Error See Download Handler Error !!HOT!!

When a download fails, the RemoteProviderException contains errors that can be used to determine how to handle the failure.The RemoteProviderException is either the AsyncOperationHandle.OperationException or an inner exception. As shown below:

Error processing data. The request succeeded in communicating with the server, but encountered an error when processing the received data. For example, the data was corrupted or not in the correct format.

Exceptions are errors that break your application execution unexpectedly. In Unity development, C# is used for scripting; therefore, it is nice to know the most common C# exceptions you can expect during your Unity application development.

These are all off the shelf parts from Unity, with the exception of theFileLoaderCompleteEventArg but just assume that we use that to pass off thedownloaded bytes as an array eg: byte[]. Notice this returns an IEnumeratorand utilizes yield statements so it should be run in a Coroutine. Whathappens here is that the UnityWebRequest will open up a connection to thegiven path, download everything into a byte array contained within theDownloadHandlerBuffer. The FileComplete event will fire if there are noerrors, sending the entire byte array to the subscribing class. Easy, right? Forsmall files, sure. But we were making a 360 Video player. Our max resolution was1440p. The first sample files we got for testing were bigger than 400MB. TheiPhone 7, with 2GB of RAM, took it like a champ. The iPhone 6, with 1GB of RAM,crashed like a piano dropped from a helicopter.

The error handler configuration requires an instance that implements IAnalyticsErrorHandler which will get called whenever an error happens on the analytics client. It will receive a general Exception, but you can check if the exception is a type of AnalyticsError and converts to get more info about the error. Checkout here to see a full list of error types that analytics throws.

You can use this error handling to trigger different behaviours in the client when a problem occurs. For example if the client gets rate limited you could use the error handler to swap flush policies to be less aggressive:

Plugins can also report errors to the handler by using the .ReportInternalError function of the analytics client, we recommend using the AnalyticsErrorType.PluginError for consistency, and attaching the exception with the actual exception that was hit:

Reasons to change this behavior:

- Clutters analytics data as it's reported as the same severity as issues that are more important, e.g., a Scene failed to load.

- Already have UnityWebRequest.error for handling errors, confusing to also log it as a unity error.

- Different behavior to other platforms, as Editor and iOS don't log unity errors for UWR failures.

Android: Improve error messages for cases where android application fails to load libmain.so. Previously it was printing "Unable to find main", now it will print "Failed to load 'libmain.so', the application will terminate.", additionally it will print exception from System.loadLibrary with detailed info, where the application was looking for libmain.so

Web: UnityWebRequest: the new result property will tell if request is completed successfully or what kind of failure occurred. DownloadHandler class also has new property error, which will give descriptive message if a failure occurred when processing received data.

Thanks for the patience. Could you please follow this document -- SDK error handling best practices to handle the error then provide the detailed error messages? The Null Reference exception can't be used to target the specific error.

In this code, the completed event is used to check the status of the response from the server. If the response is successful (i.e. there is no network or HTTP error), then the data returned by the server is accessed and used. Otherwise, an error is handled.

@Ines Yes, you are correct. The endpoint used before was correct and if the data is visible on LUIS portal then i think the AnalyseResponseElements() needs to be modified to match the analysedQuery returned from LUIS. The method might not be handling the response from LUIS causing this error. You can print the response and then make the required changes in the AnalyseResponseElements() method. This document is also not updated since 2018 but there were lot of changes on LUIS with respect to the results from the prediction endpoint, so it is likely that the document also needs an update to ensure this is working with the latest versions.

You can also use the Object view in the Profiler to inspect individual objects and their memory usage. By analyzing this data, you can narrow down the cause of the GC cache error and make adjustments to optimize memory usage in your game.

this simple solution fixed all my problems. i still see an unknown error pop in my database errorlog from time to time. since i also log the trycount, i can confirm that i never had it pop up twice in a row. e24fc04721
