TypeError : Cannot read property "length" from nullDescriptionWhen the scheduled rest call is run via Threat Intelligence Source, getting error below: TypeError : Cannot read property "length" from null CauseThe cause of this issue is due to Payload size which is more than 5mb in the rest call.See the description of 'SimpleBlocklistProcessor' script include, It says"Plain text processor, chiefly used to parse and insert processor records. Because this does not use streaming APIs, the payload must be less than 5 MB for attachments."ResolutionTo resolve such error, need to modify by replacing line 23 of 'SimpleBlocklistProcessor' script include (raw = new GlideSysAttachment().getContent(gr); ) with below code : var attachmentAPI = new GlideSysAttachment();var contentStream = attachmentAPI.getContentStream(attachmentId);var reader = new GlideTextReader(contentStream);var lines = [];while ((ln = reader.readLine()) != null) {lines.push(ln);}raw = lines.join(""); This way we can process huge payload (>5 mb) with getContentStream.
