Error: not able to deploy contract at remote server

[qiuhuiming]

I try to set up the quorum network at my remote server using Docker according to "https://github.com/synechron-finlabs/quorum-maker/wik".

In order to access the Web UI, I changed the docker-compose.yml through adding the "ports" argument. For example:

  node1:
    container_name: node1
    image: syneblock/quorum-maker:2.6.0_2.6.5
    working_dir: /node1
    command: ["bash" , "start.sh"]
    volumes:
      - ./node1:/node1
      - ./node1:/home
      - ./node1:/master
    networks:
      vpcbr:
        ipv4_address: 10.50.0.2
    ports:
        - 22002:22004

And then I accessed http::22002 and succeed. However, I failed to upload the contract file.

The docker log is like this:

I see what the problem is. My contract file requires different compiler version. I found this by executing this command in the container of node1:

solc --combined-json abi,bin <my_filename>

Then I see the output is not JSON format with the version problem, so this line will panic.

I think it is neccesary to handle this exception and gracefully response to the web brower.
