How to properly include a JSON string as an environment variable in Azure pipeline yaml file?

I have the following environment variable that I have included in my azure-pipelines.yaml file:

  - name: myVariable
    value: '{"key1":"value1","key2":"value2"}'

The problem is the way that the pipeline is passing along this variable. When echoed, it looks like this: key1:value1 key2:value2, and since my application is expecting a JSON string, this is throwing JSONDecodeError("Extra data", s, end).

I tried formatting the variable differently with escape characters as follows:

{"key1":"value1","key2":"value2"}

which resulted in this echoed variable as I would expect:

{"key1":"value1","key2":"value2"}

but my application code threw this error JSONDecodeError: Expecting property name enclosed in double quotes. I added double quotes as follows:

"{"key1":"value1","key1":"value1"}"

but then received the following error: While parsing a quoted scalar, find unknown escape character.

It seems like the pipeline file doesn’t like the format of the variable. I’m wondering if there is an issue with the way that I have formatted the variable. I’d like for the variable to be passed the way I have described above, but if all else fails I could pass it in a more agreeable format and have my application code parse it. Would appreciate any thoughts, thanks.

    Did you try this? "{"key1":"value1","key2":"value2"}"

    Not sure how your application invokes the json. Check the variable doc:

    Variables are always strings. If you want to use typed values, then you should use parameters instead.

    you could use convertToJson expression, it takes a complex object and outputs it as JSON.

    parameters:
  - name: listOfValues
    type: object
    default:
      this_is:
        a_complex: object
        with:
          - one
          - two

steps:
- script: |
    echo "${MY_JSON}"
  env:
    MY_JSON: ${{ convertToJson(parameters.listOfValues) }}

    output:

    If you use it for variable:

    variables:
  - name: myVariable
    value: '{"key1":"value1","key2":"value2"}'

steps:
- script: |
    echo "${newVar}" 
  env:
     newVar: ${{ convertToJson(variables.myVariable) }}

    Output:

    You could check to use parameter or variable for definition, and invoke ${MY_JSON} in your application.
