ECS Fargate task unable to acquire fs store filesystem lock

[codevbus]

I'm trying to run jsreport 4.3.1 on an ECS cluster running Fargate. I'm currently getting the following error in the task logs:

Current Dockerfile

WORKDIR /app

COPY --chown=jsreport:jsreport data/ /app/data

COPY --chown=jsreport:jsreport jsreport.config.json /app

VOLUME [ "/app/data" ]

Relevant ECS task definition configuration:

I'm running 4.3.1 at Fargate without any problem.

We have some differences in config and Dockerfile, here are some:

• I'm also copying my license file. This is probably not the problem, but I think you'd want to do this.
  COPY --chown=jsreport:jsreport license-key.txt /app

• I don't have the `VOLUME ["/app/data"] in my Dockerfile

• I'm not setting WORKDIR in my Dockerfile. But I do RUN cd /app which is almost the same

• I have the following under Extensions in my config file:

    "fs-store": {
      "sync": {
        "usePolling": false
      }
    }

If I recall correctly this was to mitigate some sync problem on MacOS with Docker, i.e. I don't think this is the problem either, but I added it here since it is FS-related.
