Sending multiple Attachements via Mail by pre-using the "Select-Operator"

Posted on by LukasBr

Hello Folks,

I am trying to set up a flow which sends an E-mail with multiple attachements. I found some threads which descibes the datapreparation process via Apply-to-each loop.

https://flow.microsoft.com/de-de/blog/multiple-attachments-single-email/

http://saltypc.com/?p=619

In my experience the Apply-to-each approach consumes a lot of time. Instead I would like to use the Array-"Select" operator and set the output of this operation as the new attachement input for the "Send an E-Mail" Operation.

Sadly this doesn't seem to work for me. I am getting the error that

-> "Parameter 'Attachment Name' cannot be null or empty.

Below you can see a snapshot from the test-input of the step "Send an E-Mail" the Attachements-Input seems for me valid.

[...] okmark:_MailOriginal'>\n\n<o:p> </o:p>\n\n</div>\n\n</body>\n\n</html>\n","Attachments":[{"Attachment Name":"Test-250724.pdf","Attachment Content":"JVBERi0xLjQKJYCAgIAKMSAwIYWlsZXIKPD [...] MiAwIFIgL0lEIFs8kEDI5NDU4CiUlRU9GDQo="},{"Attachment Name":"Test_Sign.svg","Attachment Content":"PD94bWbj0 [...] DQo8L3N2Zz4="}],"Importance":"Normal","IsHtml":true}}

Could you give me an idea which might be wrong here in this approach?

Best Regards,

Lukas

Hi @GBLukas

Can you please post a screenshot of the flow?

Can you ensure that the attachments array has the attributes as:

{

"Name" : "filename.extension",

"ContentBytes" : contentbytes

}

You need to ensure that the attachments array that you are creating has these attributes (Name and ContentBytes as mandatory).

If you could share a screeshot we might better identify the issue and assist you with this.

Hope this Helps!

Hi @yashag2255

I wasnt beware of the fact that the array must have the specific key Names "Name" and "ContentBytes". I changed the Key-Names and now its working like a charme.

Thank you very much!

Best Regards,
Lukas
