gm identify: Request did not return an image (node alpine docker)

[olalonde]

After switching to an alpine based image in docker, I'm getting this error:

Error: Command failed: gm identify: Unable to open file (/app/gmiv8vvd) [Invalidargument].
  gm identify: Request did not return an image.

Posting here in case anyone faced that issue before.

haha. Here is error:

cropImg err: { Error: Command failed: gm identify: Insufficient image data in file (image-temp.jpg).
gm identify: Request did not return an image.

cropImg err: { Error: Command failed: gm identify: Empty input file (image-temp.jpg).
gm identify: Request did not return an image.

cropImg err: { Error: Command failed: gm identify: Not a JPEG file: starts with 0x00 0x00 (image-temp.jpg).
gm identify: Request did not return an image.

I try to crop lots of imgs, don't know how to track the debugger.

Intermittent Error Message:

Error: Command failed: gm identify: Unable to open file (/tmp/gm4yFeyx) [Invalid argument].
gm identify: Request did not return an image.

Code Snippet:

const convertPDFToImages = async (
    pdfFile: Express.Multer.File
) => {
    const options = {
        density: 300,
        width: 1200,
        height: 1800,
        format: 'png',
        savePath: pdfFile.destination,
        saveFilename: pdfFile.filename.replace(/\.[^/.]+$/, ''),
    };    
    const convert = fromPath(pdfFile.path, options);

    try {
        const images = await convert.bulk(-1);
        console.log('images==>', images);
    } catch (error) {
        console.error('Error during conversion:', error);
    }
}

The issue occurs intermittently during the conversion of a PDF file to PNG images using GraphicsMagick (gm) within a Node.js environment. The error message suggests a problem with opening the temporary file (/tmp/gm4yFeyx) and indicates that the identify request did not return an image.

• Node Version: node:14.5.0-alpine
