Any reference for understanding attachment component functionality like where it is stored or how to get it on form submission ?
@shafali If you are using form portal submit it will be in CRX only, check content/forms/fp, and then respective user node. You can use the guide Bridge to play with attachment object
The attachments to the form are stored under the payload folder if the form is configured to trigger AEM workflow
The attachments are also stored under a tmp location in the AEM repository
the attachments will be cleaned up after certain time
