Azure ML mounting Storage Account

Hello,

We are trying to mount an Azure Storage account in Azure ML. This works perfectly fine, until we start a child run. In the logs of the child run, we can see the following:
Set Dataset input__c79bd306's target path to /mnt/batch/tasks/shared/LS_root/jobs/ml-studio-01/azureml/train_classification_model_20210909_fr_1631216080_e3eca838/wd/input__c79bd306_f7faa3c3-938e-4cfc-950b-c91c9827dfa4

But when we try to access the mount, we get the following error: '/mnt/batch/tasks/shared/LS_root/jobs/ml-studio-01/azureml/train_classification_model_20210909_fr_1631216080_e3eca838/wd/input__c79bd306_f7faa3c3-938e-4cfc-950b-c91c9827dfa4': No such file or directory

The code to start the child run can be found below.
Thank you for your help.

`child_config = ScriptRunConfig(source_directory='.',
script='src/main_child.py',
arguments=arguments,
environment=environment,
docker_runtime_config=DockerConfiguration(use_docker=True),
compute_target=compute_target)
run.submit_child(child_config)`
