GraphicsMagick/ImageMagick: gm couldn't be executed

I'm using this API to get a pdf and this is a snippet of my current set-up:

    formData.append("file", fs.createReadStream("dirname/filepath"))
    const response = await axios.post(
      "https://api.pspdfkit.com/build",
      formData,
      {
        headers: formData.getHeaders({
          Authorization: "Bearer " + LIVE_API_KEY,
        }),
        responseType: "stream",
      }
    )

    await response.data.pipe(fs.createWriteStream(filename))
    const filepath = "dirname/filename"
    const options = {
      density: 100,
      saveFilename: "untitled",
      savePath: "./images",
      format: "png",
      width: 600,
      height: 600,
    }
    setTimeout(() => console.log("times up!"), 1000)
    const convert = fromPath(filepath, options)
    const pageToConvertAsImage = 1

    const result = await convert(pageToConvertAsImage, {
      responseType: "image",
    })
    console.log({ result })

I was getting the pdf from the API mentioned above but I'm getting this error with pdf2image:
