DaniMadmolil · January 23, 2023, 5:59pm

hello. i want to use a external task to upload pdf file to camunda and set it as a process variable using nodejs with help of camunda-external-task-client-js

client.subscribe("generatepdf", async function ({ task, taskService }) {
  
  const processVariables = new Variables();

  const file = await new File({
    localPath: "./assets/a.pdf",
    mimetype: "application/pdf",
  }).load();
  processVariables.set("doc", file);
  await taskService.complete(task, processVariables);
});

I already try this with no luck,
i want to upload file as pdf file to camunda variable (variable with type “File”)

Have you compared your work with the example?

github.com

camunda/camunda-external-task-client-js/blob/master/examples/order/index.js#L43

      
        
            // create a Client instance with custom configuration
            const client = new Client(config);
            
            
// susbscribe to the topic: 'invoiceCreator'
            client.subscribe("invoiceCreator", async function ({ task, taskService }) {
              // Put your business logic
              // complete the task
              const date = new Date();
              const invoice = await new File({ localPath: "./assets/invoice.txt" }).load();
              const minute = date.getMinutes();
              const variables = new Variables().setAll({ invoice, date });
            
            
  // check if minute is even
              if (minute % 2 === 0) {
                // for even minutes, store variables in the process scope
                await taskService.complete(task, variables);
              } else {
                // for odd minutes, store variables in the task local scope
                await taskService.complete(task, null, variables);
              }
            });

The way the variables are being set are different…

Not that I’m saying that it’s the solution, but it might take you down the right path.
