Attaching multiple files to Approval Email

[mwackers]

I'm building a flow.

I been successful at finding the files in the subfolder and getting the contents in an array. 

Here is how I set up the Attachments in the Approval Email

{
    "inputs": {
        "name": "FileAttachmentContent",
        "value": "}\n\"Name\":@{items('Apply_to_each_4')?['{FilenameWithExtension}']},\n\"ContentBytes\":@{base64(outputs('Get_file_content')?['body'])}\n}"
    },
    "metadata": {
        "operationMetadataId": "1fb9c83b-b301-488e-9904-0c14a746aec8"
    }
}

Here is the test run of the flow with the errors

The format of your append to array statement is wrong.  It should look like this

The $content should be just the output of the Get File content, without converting to Base64

I tried your suggestion as follows:

{
    "inputs": {
        "name": "FileAttachmentContent",
        "value": "}\n\"Name\":@{items('Apply_to_each_4')?['{FilenameWithExtension}']},\n\"content\":@{body('Get_file_content')}\n}"
    },
    "metadata": {
        "operationMetadataId": "1fb9c83b-b301-488e-9904-0c14a746aec8"
    }
}

Go the following error

Error

Action 'Start_and_wait_for_an_approval' failed

The request failed. Error code: 'InvalidRequestContent'. Error Message: 'The request content was invalid and could not be deserialized: 'Error converting value

I believe you have an error in your append to array action. This is the peek code for the action in my flow

{
    "inputs": {
        "name": "varFileArray",
        "value": {
            "content": "@body('Get_file_content')?['$content']",
            "name": "@{triggerBody()?['{FilenameWithExtension}']}"
        }
    },
    "metadata": {
        "operationMetadataId": "b2ab9ba2-5062-4ef7-865d-b3f477d13b4e"
    }
}

If you look at your screenshot of the same peek code you can see that value: is a string in yours, not a record.  I suspect your opening brace is backwards and that is causing it to misfire.

That certainly correct a problem.

The strange thing is that keeps running never getting the first file attached, but also not generating an error.

The good news is that I'm getting emails with attachments.

The bad news is that they don't open.

For example:

Here is the code that gets the file content into an array for attachment to an email.

{

    "inputs": {

        "name": "FileAttachmentContent",

        "value": {

            "Name": "@items('Apply_to_each_4')?['{FilenameWithExtension}']",

            "Content": "@body('Get_file_content')?['$content']"

        }

    },

    "metadata": {

        "operationMetadataId": "1fb9c83b-b301-488e-9904-0c14a746aec8"

    }

}

And here is what it is spitting out:
