How can I make the "field_media_document_display field be filled with a 1? Although I have the Files displayed by default set as true and when I manually add one it defaults to 1 , when I use the step one process it put s a null there . Since it has a null the next time a user tries to change the name it doesn't work.
I am using the Migrate File Entities to Media module, this is my code in step 1. where can I add something to make it fill in the field_media_document_display_field as a 1 ?
field_media_document/title: title
field_media_document/target_id:
    plugin: media_file_copy
    move: FALSE
    reuse: TRUE
    path: 'public://grants/'
In media-migration-step1.yml.twig I see:

So should be:
field_media_document/display: TRUE
field_media_document/target_id:
    plugin: media_file_copy
    move: FALSE
    reuse: TRUE
    path: 'public://grants/'

If still not, try:
field_media_document/display:
    plugin: default_value
    default_value: TRUE
field_media_document/target_id:
    plugin: media_file_copy
    move: FALSE
    reuse: TRUE
    path: 'public://grants/'
