Hey all!!
I am trying to upload PDF attachment by using function node. Basically, I got the base64 string of a PDF file from web hook. I will convert it and upload. Initially I used http request node but I got timeout exceeded error. So, I decided to use function node to upload the pdf by using axios. I installed axios and form-data node modules. But when I try to upload PDF, I got 500 error. Can anyone help me? What I am doing wrong.
Check below
Message": "Request failed with status code 500",
"name": "Error",
"stack": "Error: Request failed with status code 500 at createError (/usr/local/lib/node_modules/n8n/node_modules/axios/lib/core/createError.js:16:15) at settle (/usr/local/lib/node_modules/n8n/node_modules/axios/lib/core/settle.js:17:12) at IncomingMessage.handleStreamEnd (/usr/local/lib/node_modules/n8n/node_modules/axios/lib/adapters/http.js:269:11) at IncomingMessage.emit (node:events:538:35) at endReadableNT (node:internal/streams/readable:1345:12) at processTicksAndRejections (node:internal/process/task_queues:83:21)",
My Workflow
var axios = require('axios');
var FormData = require('form-data');
const file = $node["Set1"].json;
const url = $node["appConfig"].json.envUrl+'/orgs/'+$node["appConfig"].json["orgKey"]+'/projects/'+$node["appConfig"].json["projectKey"]+'/activities/'+$node["payload"].json["adds"][0]["activityKey"]+'/pdfs'
const token = $node["Auth_Token"].json["token"];
const metadata = {
activityId:$node["payload"]?.json?.adds?.[0]?.activityTypeActivityTypeId,
idempotencyKey:$node["Attachment_Payload"]?.json?.idempotencyKey,
sha1:$node["SHA1"]?.json,
};
var data = new FormData();
data.append('pdf', Buffer.from(file.pdf, 'base64'));
data.append('activityId', metadata.activityId);
data.append('idempotencyKey', metadata.idempotencyKey);
data.append('sha1', metadata.sha1);
var config = {
method: 'post',
url: url,
headers: {
'content-type': 'multipart/form-data',
'Authorization': `Bearer ${token}`,
},
maxContentLength: 10000000,
maxBodyLength: 10000000,
data : data
};
console.log(config);
const result = await axios(config)
.then(function (response) {
console.log(JSON.stringify(response.data));
let respData = [];
respData.push(response.data);
return [{'respData': respData}];
})
.catch(function (error) {
console.log(error);
return [{'failed': error}];
});
return [{'result': result}];
Share the output returned by the last node
The file upload node is last one. It returns the same error which I shared.
