Unable to upload a Base64 encoded image using v20+ of the API.

I can upload encoded image data using v19 of the API.  Any idea what the change is that I am missing?  I get the following error: 

 

Invalid data specified, the provided data does not seem to be a valid image: [B@574b1c

and

INVALID_DATA_URI

 

Again, if I use v20/21 I get the error, if I use v19 then all goes well and I see my image.

 

Thanks

You can post an example of your request? sounds like this is an image in a rich text field ?

Correct,  Within Adobe Flex, I have encoded a jpeg to Base64.  Since Rich Text Fields are not supported by the sync in the Force For Flex toolkit, I chose to upload seperately via a standard com.salesforce.connection.  I am using the following sandbox URL.

 

https://test.salesforce.com/services/Soap/u/19.0

 

if I use 20.0 or 21.0 I get the error mentioned above.  The string that I am passing to the create() in my custom object to a RichText Field looks like:

 

<img alt="Home Pict" src="data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD/2wCEAAYEBQYFBAYGBQYHBwYIChAKCgkJChQODwwQFxQYGBcU
Fh .....Many more < 32000......." />

 

Works like a charm with 19.0.

Posted an update, wondered if you had any further thoughts.  Thanks

I haven't been able to reproduce this yet. can you provide some more details (e.g. image size/format). If you have a standalone app that demonstrates this, that'd be great.

Simon, My apologies.  I left out the critical piece of info.  I am working with the forceforflex toolkit within Adobe FlashBuilder 4.  I have been able to do quite a bit creating an offline AIR app.  Here is the declaration:

 

        <flexforforce:F3DesktopApplication id="app"
                                           statusChanged="statusChangedHandler(event)"
                                           loginComplete="_login.loginCompleteHandler(event)"
                                           loginFailed="_login.loginFailedHandler(event)"
                                           sessionExpired="_login.sessionExpiredHandler(event)"
                                           serverUrl="https://test.salesforce.com/services/Soap/u/19.0"
                                           requiredTypes="Account,Contact"/>

 

If I change the serverURL to a more recent versiojn of the API the syncing of the data fails as mentioned above. 

 

I have also tried with a driect connection rather than the built in sync:

 

 

private var sfdcWebTest:Connection;

private function login():void

{sfdcWebTest.serverUrl= "https://test.salesforce.com/services/Soap/u/19.0";
            var lr:LoginRequest = new LoginRequest();
            lr.server_url = sfdcWebTest.serverUrl;
            lr.username = _username;
            lr.password = _password;
            lr.callback = new AsyncResponder(loginComplete, messageHandler);
            sfdcWebTest.login(lr);

}

private function loginComplete ():void

{var imageSO:SObject = new SObject("Image__c");
                        imageSO.imageData__c = '<img alt="Home Pict" src="data:image/jpeg;base64,'+_encodedImagesArr[i].encodedImage+'" />';
                        imageSO.imageTypeId__c = _unsyncedImages.imageDataArr[j].imageTypeId;
                        imageSO.imageType__c = _unsyncedImages.imageDataArr[j].imageType;
                        imageSO.originalImageId__c = _encodedImagesArr[i].id;
                        aSo.push(imageSO);

sfdcWebTest.create(aSo, new AsyncResponder(imageInsertComplete, messageHandler));

}

 

 

 

When I use an API higher than 19 the create() or update() on the rich text field fail.

 

Thanks again.

Any Luck with this? I'm also having the same issue here.

I don't know if it's related because your stuff looks much different than mine but my solution is posted here: https://developer.salesforce.com/forums/?id=906F00000008pzaIAA

The different problems I had was android was word wrapping (which the pc browser did not care about but salesforce did) and some formatting issues
