Hello guys,

i have a problem with attachments in "Send an email V2" in a flow.

i generate word documents with "Word online" and save it in sharepoint.

My flow can generate between 1 and 4 documents, so I created a variable-array and use the function "Append to array".

code view :

{
  "type": "AppendToArrayVariable",
  "inputs": {
    "name": "VarAttachments",
    "value": {
      "Name": "@{outputs('Create_file_-_Attestation_Laptop_Word_Avocats')?['body/Name']}",
      "ContentBytes": "@{body('Get_file_content_-_Attestation_laptop_Word_Avocats')?['$content']}"
    }
  },
  "runAfter": {
    "Get_file_content_-_Attestation_laptop_Word_Avocats": [
      "Succeeded"
    ]
  }
}

I receive the attachments with good name and the right extension (docx), but all file are corrupted, i don't understand why...

I have try to modifify my "ContentBytes" in append my array with :

-content from get file content

"ContentBytes": "@{body('Get_file_content_-_Attestation_laptop_Word_Avocats')?['$content']}"

-generic value from get file content

"ContentBytes": "@{body('Get_file_content_-_Attestation_laptop_Word_Avocats')}"

-content from "popupale a microsoft word document"

"ContentBytes": "@{body('Populate_a_Microsoft_Word_template_-_Laptop_Avocats')}"

Every time, the result is the same: my attachments have the correct names and the .docx extensions, but the files are corrupted and unreadable.

Please help me :(

@GreguS,

In my case also getting attachment from sharepoint site and appending to array as shown but in your case where is for all loop (apply to each) i cannot see loop action.

@MS.Ragavendar

thank you for your reply, i don't use "for each" in this flow. i use a "condition / not empty" sharepoint value for create a word document

@GreguS The issue is that you're using the old array format for attachments. I don't know when or why it changed, but attachment arrays must now be in this format:

{ "contentbytes": { "$content-type": "@{outputs('Get_Attachment_(V2)')?['body/contentType']}", "$content": @{outputs('Get_Attachment_(V2)')?['body/contentBytes']} }, "Name": "@{outputs('Get_Attachment_(V2)')?['body/contentBytes']}" }

You'll want to change the dynamic content in that example to match yours. This will prevent attachments from being corrupted files upon receipt.

Note that there are no quotes around the value containing ContentBytes.
