Hi Team,

 

I have been breaking my head from the last 3 hours as I am not able to upload files/images to the SharePoint library using PowerApps through power automate. I have followed the below article step by step advised in article http://johnliu.net/blog/2019/4/flowninja-hack-87-lock-microsoft-flow-powerapps-trigger-to-upload-images-to-sharepoint-with-ease but the flow was getting failed with the error as: "Unable to process template language expressions in action 'Create_file' inputs at line '1' and column '2279': 'The template language function 'base64ToBinary' was invoked with a parameter that is not valid. The value cannot be decoded from base64 representation.'"
I have also tried the video blog https://www.youtube.com/watch?v=ZXWyDgDEHPo by @RezaDorrani but no luck.

    Jcook,

     

    Would you be able to share the flow with me? I am a little confused about your proposal.

     

    Regards,

    @KrishnaV 

     

    Right, my proposed suggestion is just an example.

     

    You can use the Form in Power Apps to upload the Attachment into SharePoint. The flow can be kicked off using the onSuccess property of the form.

    The flow does not have to add the document to a library. You can use my suggestion to get the File Content of the file.

     

    After the last step, you will be able to call the dynamic content for File ContentAfter the last step, you will be able to call the dynamic content for File Content

     

    The SharePoint list just acts as an intermediary to easily get the attachment out from Power Apps.

     

    After you get the Attachment content, you can put anywhere.

    unfortunately no 😞, I need this as a separate app not with the form in the list or a library.

    I am calling the flow with the input values as follows:

    'UploadfilestoSharepoint-2'.Run(UploadFile.Media,UploadFile.FileName)

    Hi @KrishnaV 

    What I have done in the past, was upload a attachment from Power Apps to SharePoint as a list item, using a Edit form in Power Apps.

     

    Than on Success of the form property, I would trigger a flow to grab that attachment from the list and create a file in a Document Library.

    Hi @KrishnaV,

     

    Could you share the code of the "Upload" button in PowerApps?
