Not getting the right base64 output string

Posted on by BuzzityBuzz

I have a PowerApps V2 connector that takes in file as an input (image to be specific). The "File Content contentBytes" output of this connector comes out with correct base64 encoding but I having issues passing this to 'Create item' SharePoint connector where the purpose is to create a list item and save this base64 string to a field in a list. The output of the 'Create item' connector in the 'ImageURI' is not correct. Please see below images.

The above File Content contentBytes is what I want to save in the SharePoint list.

Above two images is of the SharePoint connector. First one is of the Input section and the other is Output where you can see the ImageURI field is not correct.

I hope I have provided information. Any help or suggestion is highly appreciated.

Set a string variable to the value you want, the create or update item with that variable. Should work just fine. Also for it to be readable, be sure to add
data&colon;image/jpeg;base64,
before the Base64 string, as otherwise powerapps image wont read it, and you can save it as a jpeg, or change jpeg to png if that's the format you want.

Trying to take in the input from the PowerApps V2 connector to init a variable and the value comes out to be like this. I am passing triggerbody()['file']['contentBytes'] in the value of Initialize variable connector.

I mean, yea, base64 is a string of text, if you want to add it as an attached file thats different and cannot be stored in a multiline column.

I do not want to store it as a file. All I want is to store the base64 text into a multiline text column that is an output of the Powerapps connector which takes the image file as an input. I hope this clears a bit.
