Problem in passing JSON string in environment to shell module

[Nirav Radia]

I am trying to pass JSON string in environment.

- name: Start {{service_name}}
  shell: "<<starting springboot jar>> --server.port={{service_port}}\""
  environment:
    - SPRING_APPLICATION_JSON: '{"test-host.1":"{{test_host_1}}","test-host.2":"{{test_host_2}}"}'

test_host_1 is 172.31.00.00

test_host_2 is 172.31.00.00

But when in spring logs, I get JSON parse exception where it prints

Caused by: com.fasterxml.jackson.core.JsonParseException: Unexpected character (''' (code 39)): was expecting double-quote to start field name
 at [Source: {'test-host.1': '172.31.00.00', 'test-host.2': '172.31.00.00'}; line: 1, column: 3]

As seen, double quotes are converted to single quotes !!!

I tried escaping double quotes but with no luck.

Any idea why it happens, or any work around?

Thanks,

Nirav

As a workaround you can add a space after the first single quote like this
' {"test-host.1":"{{test_host_1}}","test-host.2":"{{test_host_2}}"}'

No idea why, but it looks like a bug to me.
