TypeError: The "iterable" argument must be an instance of Iterable. Received an instance of Object

Hello team,
I've the following configuration on Typescript:

const eannaContainer = await new GenericContainer(
    '<server name>/eanna/release:4.3.0')
    .withNetwork(network)
    .withNetworkAliases('eannahost')
    .withExposedPorts({
        container: 8080,
        host: 6080
    })
    .withCopyFilesToContainer(
        [{source: rootE2gFolderPath + '/config/eanna/logback-spring.xml', target: '/deployments/config/logback-spring.xml'}])
    .withEnvironment({
        ...eannaEnv,
        JAVA_MAX_MEM_RATIO: '100',
        JAVA_INIT_MEM_RATIO: '50'
    })
    .withStartupTimeout(300000) // wait 5 min
    .withWaitStrategy(Wait.forHttp('/actuator/health', 8080))
    .start();

But when I trigger it with our CI/CD pipeline, i get the following exception:
[21:33:27.404+02:00] - TypeError: The "iterable" argument must be an instance of Iterable. Received an instance of Object

Note: this problem occurs only with the version testcontainers 10.23.0 or 10.24.0 but not with the version 10.21.0.
Do you know what you have changed recently that could cause this regression?
Thanks a lot

Hi, are you using docker or some other container runtime? Which OS?

[lucmoulin]

Hi,
Yes this container creation is triggered by Jenkins and Jenkins is runing as a docker container. I guess it's a linux image.
Thanks

Note: this problem occurs only with the version testcontainers 10.23.0 or 10.24.0 but not with the version 10.21.0.

Are you sure you can reproduce the issue in 10.23.0 but not in 10.22.0? The 10.23.0 release did nothing other than add a feature to the Postgres container: https://github.com/testcontainers/testcontainers-node/releases/tag/v10.23.0

I've tested with the version 10.26.0 and the issue is still present.
The problem comes from the setup of the file to copy: withCopyFilesToContainer
On my environment I've defined the following configuration:
.withCopyFilesToContainer(
[{source: rootE2gFolderPath + '/config/eanna/logback-spring.xml', target: '/deployments/config/logback-spring.xml'}])

Could you please double check in the code this piece of code:
if (this.filesToCopy.length > 0 || this.directoriesToCopy.length > 0 || this.contentsToCopy.length > 0) {
const archive = this.createArchiveToCopyToContainer();
archive.finalize();
await client.container.putArchive(container, archive, "/");
}

Thanks a lot
