Base 64 to attachment conversion

[supriya pratapa]

We have a base64 response and want to convert this base64 into attachment and attach it to a record in ServiceNow.

(function() {

    var base64Payload = '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';

    var base64Bytes = GlideStringUtil.base64DecodeAsBytes(base64Payload);

    var ByteArrayInputStream = Packages.java.io.ByteArrayInputStream;

    var inputStream = new ByteArrayInputStream(base64Bytes);

    var gr = new GlideRecord('incident');

    var recordSysId = '57af7aec73d423002728660c4cf6a71c';

    if (!gr.get(recordSysId)) {

        gs.error('Record not found: incident sys_id=' + recordSysId);

        return;

    }

    var gsa = new GlideSysAttachment();

    gsa.write(gr.getUniqueValue(),gr.getTableName(),'test10.pdf', 'application/pdf', inputStream);

    gs.info('Attachment created successfully.');

})();

The attachment is attached to the record but unable to open the file.

I already informed the script I shared should work fine provided you give correct base64 for PDF

The same script worked for me in global scope

-> I took base64 of some pdf file using this website "https://base64.guru/converter/encode/pdf"

-> then background script ran and file attached and when I opened the file, data is seen

see the gif attached
