error: thread constructor failed: Resource temporarily unavailable

[JounQin]

import AsposePdf from 'asposepdfnodejs'
const AsposePdfModule = await AsposePdf()

const json = AsposePdfModule.AsposePdfToDocX(
  new URL('Doom-zh.pdf', import.meta.url).pathname,
  new URL('Doom-zh.docx', import.meta.url).pathname,
)

console.log(
  'AsposePdfToDocX => %O',
  json.errorCode == 0 ? json.fileNameResult : json.errorText,
)

If you want, I can send the .pdf via email.

I'm then trying aspose-pdf-js on the web instead, but

You need to use encrypt_lic.html to get an encrypted license file for running in full-featured mode.

Do I need .lic-file only for prototyping? Without it, I'm getting /aspose.enc 404 (Not Found) expected, with unexpected:

For example_worker.html, it results same as Node.js:

Error: thread constructor failed: Resource temporarily unavailable

Thank you for your patience!

Could you please first check whether the input file path is valid and accessible by running this snippet:

import fs from 'fs';
const inPath = new URL('Doom-zh.pdf', import.meta.url).pathname;
console.log('exists?', fs.existsSync(inPath), inPath);

If the output shows false, the issue is most likely that the file cannot be found or accessed at the given path - this often causes the thread constructor failed: Resource temporarily unavailable error.
Please make sure the file exists in the same folder as your script or provide an absolute path.

Thank you for the additional details!

The /aspose.enc 404 message is expected if you dont use a license file - thats fine and only means the library is running in evaluation mode.

However, the actual problem is shown by these two lines:

ErrnoError { errno: 44, message: "FS error" }
Uncaught TypeError: Failed to execute 'readAsArrayBuffer' on 'FileReader':
parameter 1 is not of type 'Blob'

This indicates that the file being passed to the function (for example in example.html) is not a valid Blob/File object.
In other words, the FileReader cannot read it because it`s not a file selected from the element.

Please make sure you:

Select a real PDF file using the file picker in the demo ().

Pass that file object to readAsArrayBuffer(), e.g.:

const file = document.getElementById("fileInput").files[0];
reader.readAsArrayBuffer(file);

Run the example from a local server (not file://), e.g.:

npx http-server .

The license file (aspose.enc) is optional and not required for testing.

Please also review the official examples carefully to see the correct usage pattern:
AsposePdfToDocX.html
AsposePdfToDocX_worker.html
