cwebp binary does not install when running in docker image

[lee-queueone]

//build.gradle.kts
implementation("com.sksamuel.scrimage:scrimage-core:4.2.0")
implementation("com.sksamuel.scrimage:scrimage-webp:4.2.0")

I invoke my method convertToWebP

class Image {
companion object {
fun convertToWebP(fileStream: InputStream): ByteArray {
val image = ImmutableImage.loader().fromStream(fileStream)
val writer: WebpWriter
try {
writer = WebpWriter().withM(6).withQ(75)
} catch (e: Exception) {
e.printStackTrace()
throw e
}

        return image.bytes(writer)
    }
}

}

Running locally from intelliJ with amazoncorretto:21, when I invoke the WebpWriter() for the first time, it installs the binaries as expected:
c.sksamuel.scrimage.webp.WebpHandler - Installing binary at /var/folders/fr/t2msts2x4psf58xxklmsxgb00000gn/T/cwebp16223531167641905488binary

I build a docker image with the same runtime. When I make the initial request to the service, it only installs the dwebp binary and then fails.

I tried to follow the instructions at https://sksamuel.github.io/scrimage/webp/ to override some of the behaviour, but it doesn't seem to work.
I've tried things like invoking the installer method at app startup - this actually shows that the cwebp binary installed at some directory, but the same error happens.
I've also tried to install the webp tools during the build process and copy them into a directory, and override the system property with that directory in hopes it would find the binary files.

Any help is appreciated.

I use webp inside docker, so I know it works in general.
What error message are you seeing ?
