write() function of GlideSysAttachment() not working

[Saquib Mohammed]

I have written below script as a Scripted REST resouce in Global scope. However, the write function doesnt work

var queryParamsVar = request.queryParams;
var attachment = new GlideSysAttachment();
var correlationId = queryParamsVar.CorrelationId[0];
var grIncTask = new GlideRecord('incident_task');
grIncTask.addQuery('correlation_id', correlationId);
grIncTask.query();

var fileName = queryParamsVar.FileName[0];
var contentType = queryParamsVar.ContentType[0];
var base64Encodedcontent = queryParamsVar.Base64Enc[0];
var decodedBytes = GlideStringUtil.base64DecodeAsBytes(base64Encodedcontent);
var arg = attachment.write(grIncTask, fileName, contentType, decodedBytes);
gs.info('This is a log for attachment sys_id is: ' + agr);

In the system logs, I see the below error - 

*** Script: undefined: no thrown error

and

getEventTarget() called with invalid record reference: sys_poll. for event: appsec.security.export, could have been deleted

I was trying to use writeBase64 but later found that it can used only for scoped applications. So I tried with write function but this is not doing the job either.

@Saquib Mohammed 

you need to parse the incoming request body and invoke that code that many number of times

since it works for 1 it would work for all the files as well

If my response helped please mark it correct and close the thread so that it benefits future readers.

You did not move grIncTask to the 1st record; grIncTask.next() is missing.

Thank you. That worked. However, it works for text and csv but for other content types, it is throwing error 

505 HTTP Version Not Supported

Any pointers? I am using the MIME content types from the below link

fyi... I am trying doc, xls and pdf and i am getting error for these

Try

var grIncTask = new GlideRecord('incident_task');
grIncTask.addQuery('correlation_id', correlationId);
grIncTask.query();
if (grIncTask.next()) {
		var data = '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';

		var dataAsBytes = GlideStringUtil.base64DecodeAsBytes(data);

		var sys_attachmentUniqueValue = new GlideSysAttachment().write(grIncTask, 'lock.png', 'image/png', dataAsBytes);

		gs.info('sys_attachmentUniqueValue: ' + sys_attachmentUniqueValue);
}

It should attach a small lock icon to the incident.

It works running it in scripts background.

Also try to add

gs.info('isBase64: ' + GlideStringUtil.isBase64(base64Encodedcontent));

after

var base64Encodedcontent = queryParamsVar.Base64Enc[0];

What does it print?
