If I try to insert manually, not using a variable, it works. But I need it to by dynamic. Does someone know why?  Here's my last commands.

    How does your Send Email (V2) Attachments -field look like? I remember having some trouble with that sometime but can't recall what they were.
     
    Your List of custom objects -variable looks correct.

    Example of a flow that works for me:
     
     
     
    Set variable if Attachments is empty: %[{ 'Name': FilesToCustomObj.Name, 'ContentBytes': BinaryData }]%
     
    Append to the Attachment variable: %Attachments + { 'Name': FilesToCustomObj.Name, 'ContentBytes': BinaryData }%

    List of custom objects looks like this:

     
    Send an email Attachments has just the variable:
