Failed to convert page to image

[VolckaertAchiel]

hi, i have this code in nodejs that receives a pdf, and converts it to an image, which it will respond the location on server and in base64. this works perfectly on mac. when deployed to docker it fails with:

{ message: 'Failed to convert page to image',
error:
{ Error: Command failed: convert "services/uploads/1f4ca0ff9901c719b201007b102c18e2[0]" "services/uploads/1f4ca0ff9901c719b201007b102c18e2-0.png"

let pdfImage = new PDFImage("services/uploads/" + req.file.filename)
pdfImage.convertPage(0)
.then(function (imagePath) {

.then((result) => {
let base64 = Buffer(fs.readFileSync("services/uploads/" + req.file.filename+ "-0.png")).toString('base64')
fs.unlinkSync("services/uploads/" + req.file.filename+ "-0.png");
fs.unlinkSync("services/uploads/" + req.file.filename);

                    res.status(200).json({
                        url:result.Location,
                        image:base64
                    });
                    // resolve(result)
                })
                .catch(error => {
                    console.log("error on image upload")
                    console.log(error)

                    res.status(400).json({ error: "Could not upload file" })
                });
        })

someone has an idea how to fix this?

If you can provide a minimal, runnable test case (i.e. a script and Dockerfile and an example pdf) I can investigate this.
