    Hey, the format for utilizing the document download link is as follows:


    a!linkField(
    label: "Link",
    labelPosition: "ABOVE",
    links: {
    a!documentDownloadLink(
    label: "Document Link",
    document: 8552    /* document id */
    )
    }
    )

    Is that value in appianDocId a valid document id?

    Yes it seems like it's saving the appianDocId in the database correctly

    You just shared this minimal code snippet. I cannot help you much without more context.

    Did you check the actual values in that data you seem to iterate on?

    look like that appianDocId is not exist or deleted.

    Try to search that is in objects with type UUID or ID. Im sure you will not find that.

    It seems the object you are trying to download does not exists in appian. So before passing the documentID to a!documentDownloadLink() function better to check the exitance of document in Appian using following functions:

    isobjectexists returns true if object exists in Appian.

    isobjectexists(
    "Document",
    /*documentID*/
    )    

    getcontentobjectdetailsbyid will return all the content of the object.

    getcontentobjectdetailsbyid(
    /*documentID*/
    )
