Solved: Upload file attachments to Dynamics 365 Finance

Upload file attachments to Dynamics 365 Finance

Hi,

I'm creating PowerApps which utilize the attachments control, which going to be uploaded to my Dynamics 365 Finance, with help of Flow, by using D365 Finance data connector - Create records.

This guy:

Following some tutorial, in PowerApps, when I have the attachment control, then I should do these steps:

1. Add Image control (for my temporary holder)

2. Add this code for the image property :

Last(AttachmentsCtrl.Attachments).Value

3. Add button to convert the image to binary, using this code:

Set(tempFile, JSON(ImageTemp.Image, JSONFormat.IncludeBinaryData));
Set(FileUpload, 
 Mid(tempFile,Find(",",tempFile)+1,Len(tempFile)-Find(",",tempFile)+1)
);

When I'm using it to upload a small txt file, contain only 1 word, the result of those 2 variables looks fine with me :

tempFile -> data&colon;text/plain:base64,VGVzdGluZw=="

FileUpload -> VGVzdGluZw=="

Then I will just need to create Flow to pass this FileUpload, along with my key fields (I specified all the keys correctly when I checked from the Flow)

However my Flow failed, with error -> An error has occurred. Exception has been thrown by the target of an invocation. Cannot convert the literal 'VGVzdGluZw=="' to the expected type 'Edm.Binary'.

The Output error is like this :

{

"status": 400,

"message": "An error has occurred. Exception has been thrown by the target of an invocation. Cannot convert the literal 'VGVzdGluZw==\"' to the expected type 'Edm.Binary'.\r\nclientRequestId: xxxx-xxxx-xxxx-xxxx--xxxxx",

"error": {

"message": "An error has occurred. Exception has been thrown by the target of an invocation. Cannot convert the literal 'VGVzdGluZw==\"' to the expected type 'Edm.Binary'."

"source": "xxxxxxxaos.cloudax.dynamics.com",

"errors": []

}

May I know what's wrong with this ?

Thanks.
