Morning, 

 

I am building a flow to create an item in a sharepoint list from an MS Form, attach the uploads, and then send emails with those uploads.

 

I have hit an error when sending the email with multiple attachments. It doesn't seem to recognise that there are ContentBytes.

 

Screenshots of the flow are below:

The guidance online states to make sure it is named 'ContentBytes' which I have done. The compose and initialise array both work fine and gather all the attachments. It fails once it gets to sending the email.

 

Any help would be much appreciated.
