Power Automate Power App V2 File Input error

Hi 

I am trying to create Power Automate with Power App V2 - File content input as trigger and compose as action. However, I am getting missing column error with the contentBytes.  I believe I did everything correctly.  But, I don't know why I am still getting error message below. 

Thank You in advance!

Below is the flow design.

I created it based on Shane Young video.  Power Apps Upload File v2 to SharePoint Document Library (youtube.com)

@Ruth_Dong ,

Strange unless it is something to do with your region. Mine fails without using file: If it works for you I suggest you use it.

Hi @Ruth_Dong ,

You need to refer to the UploadedImage1.Image (use your number), not the AddMediaButton1.Media. The file name is the correct reference.

@WarrenBelz , thanks for your help.  I used  UploadedImage1.Image. I am still getting the same error with UploadedImage.  and I don't have image number.

AddMediaButton1.Media may be the correct one.  Please see image properties below.

Hi @Ruth_Dong ,

I use this function extensively and always use the UploadedImage.Image reference (which is why I suggested it) and yours would be UploadedImage1.Image

flowpractice.Run(
   "himom",
   false,
   {
      file: 
      {
         contentBvtes : UploadedImage1.Image,
         name : AddMediaButtonl.Filename
      }
   }
);

Also are you getting the error before or after you run the Flow and what exactly are you doing with those Compose statements ? I also assume here that you have uploaded a file before you run the Flow.

@WarrenBelz , thank you for your support and your patience.

 

I am trying to test out the feature of Power App V2 -  input as file content.   My end goal is to create PDF file from SharePoint form and save it back to the SharePoint library.  Please see picture below.  But, I am keep getting missing column error with the contentBytes.  In fact, contentBytes already exists clearly. 

 

Therefore, I am trying to test out the feature by uploading an image.  Response to your question, the error appears before I run the flow.  And, I have already uploaded the image.

Hi @Ruth_Dong ,

I just ran this

WarrenBelz_0-1720409207777.png

using this Flow

WarrenBelz_1-1720409236429.png

and it uploaded the file perfectly.

WarrenBelz_2-1720409470585.png

 

Please have a look and see if there is anything different in the similar test example you posted.

 

 

@WarrenBelz , I followed your instructions in creating the same flow and save the file to SharePoint.  But, I am still getting the same error - missing contentBytes.   

 

I have just read other posts that are similar to this topic. Solved: [bug] Missing column contentBytes type blob (even ... - Power Platform Community (microsoft....

 

And, I followed the suggestion in the above post.  The error message is gone after I removed the word files.  Please see picture below.  And, I don't know why it works without the word file. 

 

flowpractice.Run(
    "himom",
    false,
    {
            contentBytes: UploadedImage1.Image,
            name: AddMediaButton1.FileName

    }
)

 

With the word - file, the error shows up.

@WarrenBelz , thank you for your help.  I live in CA.  Based on the post, it happens with others too.  It can be a Microsoft bug. 

@Ruth_Dong ,

I assume CA is California (not Canada) - I am in QLD AU
