CannotStartContainerError while submitting a AWS Batch Job - json

Question

In AWS Batch I have a job definition and a job queue and a compute environment where to execute my AWS Batch jobs.
After submitting a job, I find it in the list of the failed ones with this error:
Status reason
Essential container in task exited
Container message
CannotStartContainerError: API error (404): oci runtime error: container_linux.go:247: starting container process caused "exec: \"/var/application/script.sh --file= --key=.
and in the cloudwatch logs I have:
container_linux.go:247: starting container process caused "exec: \"/var/application/script.sh --file=Toulouse.json --key=out\": stat /var/application/script.sh --file=Toulouse.json --key=out: no such file or directory"
I have specified a correct docker image that has all the scripts (we use it already and it works) and I don't know where the error is coming from.
Any suggestions are very appreciated.
The docker file is something like that:
# Pull base image.
FROM account-id.dkr.ecr.region.amazonaws.com/application-image.base-php7-image:latest
VOLUME /tmp
VOLUME /mount-point
RUN chown -R ubuntu:ubuntu /var/application
# Create the source directories
USER ubuntu
COPY application/ /var/application
# Register aws profile
COPY data/aws /home/ubuntu/.aws
WORKDIR /var/application/
ENV COMPOSER_CACHE_DIR /tmp
RUN composer update -o && \
rm -Rf /tmp/*
Here is the Job Definition:

In Cloudwatch log stream /var/log/docker:

Answer 1

This error was because the command was malformed. I was submitting the job by a lambda function (python 2.7) using boto3 and the syntax of the command should be something like this:
'command' : ['sudo','mkdir','directory']
Hope it helps somebody.
