Send Attachment from One ServiceNow to Other ServiecNow Instance

[balaji_prusty1]

Hi,

I am configuring sending attachments from Incident (ServiceNow) to Other ServiceNow instances using the custom app. I configured the below script in BR. But it is always failing with 401 errors. (As below)

{"error":{"message":"Invalid file type: application/json","detail":null},"status":"failure"}

------------------------BR Script-------------------

var qry = 'table_name=incident^u_sent_flag=false^table_sys_id=' + current.sys_id;

 var att = new GlideRecord("sys_attachment");

    att.addEncodedQuery(qry);

    att.query();

    while (att.next()) {

        try {

            var r = new sn_ws.RESTMessageV2('x_mea_inte_Integration', 'Send Attachment');

            r.setStringParameterNoEscape('table_sys_id', '611b0822fbb392103bf0f471beefdc06'); // sys_id hard coded  to test

            r.setStringParameterNoEscape('table_name', 'incident');

            r.setStringParameterNoEscape('file_name', att.file_name);

            r.setStringParameterNoEscape("Accept", "application/json");

            r.setStringParameterNoEscape("Content_type", att.content_type);

            r.setRequestBodyFromAttachment(att.sys_id);

            var response = r.execute();

            var responseBody = response.getBody();

            var httpStatus = response.getStatusCode();

            gs.info("Attachment Update Responce Body : " + responseBody);

            gs.info("Attachment update status : " + httpStatus);

        } catch (ex) {

            var message = ex.message;

        }

    }

----------------------

Can someone please help with this?

Thanks in Advance.

Hi @balaji_prusty1 

The issue is not with the code, the issue is with the username password as 4-1 errors are there.

A "401 Unauthorized" error in ServiceNow integrations indicates that the system is unable to access the requested data due to invalid authentication credentials, meaning the username and password used to connect to the external system are incorrect or lack the necessary permissions to access the specified data within ServiceNow.

Also Please check what type of authentication method you are using and if it is basic  check the user profile is having proper roles or not.

Regards,
Debasis

Hi Debasis,

Its not 401 error. Credential is working. We use the same credentials (Auth 2.0) for other updates. It's giving 400 error, whichs means the Json is not supporting. File error.

Thanks All,

We are missing adding these parameters in the rest endpoint. (highlighted in red). Only sent over BR but missed adding in the end point. It's working now.
