Password Protection Encrypt and Decrypt is not working

[karthiktanj]

When we are trying to make password protection below error is occuring. Could you please provide the solution to encrypt and decrypt the pdf with password protection

Error :spawn qpdf ENOENT

TypeScript Code : var qpdf = require('node-qpdf'); var file = path.join(__dirname, 'sample.pdf');

            const options = {
                keyLength: 128,
                password: 'test1234'
            }
            qpdf.encrypt(file, options);

I am receiving the same error as well, when trying to decrypt a pdf!

events.js:292
      throw er; // Unhandled 'error' event
      ^
