Problem when constructing output with value from environment variable

Describe the bug

Invalid character when trying to construct a JSON output from a script, in this case, a specific value generates the error.

To Reproduce

Create workflow:

jobs:
  debug-without-variable:
    runs-on: ubuntu-latest
    steps:
      - name: Create JSON and set output
        id: create_json
        uses: actions/github-script@v7
        with:
          script: |
            return [
              {
                "name": "APPLICATIONINSIGHTS_CONNECTION_STRING",
                "value": "InstrumentationKey=GUID_GOES_HERE;IngestionEndpoint=https://xxx.in.applicationinsights.azure.com/;LiveEndpoint=https://northeurope.livediagnostics.monitor.azure.com/;ApplicationId=GUID_GOES_HERE"
              },
              {
                "name": "EventHubConnectionString__fullyQualifiedNamespace",
                "value": "abc"
              }
            ];

  debug-with-variable:
    runs-on: ubuntu-latest
    environment: dev-europe
    steps:
      - name: Create JSON and set output
        id: create_json
        uses: actions/github-script@v7
        with:
          script: |
            return [
              {
                "name": "APPLICATIONINSIGHTS_CONNECTION_STRING",
                "value": "${{ vars.AZURE_APPLICATIONINSIGHTS_CONNECTION_STRING }}"
              },
              {
                "name": "EventHubConnectionString__fullyQualifiedNamespace",
                "value": "abc"
              }
            ];

create an envirnoment "dev-europe" and add a single variable AZURE_APPLICATIONINSIGHTS_CONNECTION_STRING with value InstrumentationKey=GUID_GOES_HERE;IngestionEndpoint=https://xxx.in.applicationinsights.azure.com/;LiveEndpoint=https://northeurope.livediagnostics.monitor.azure.com/;ApplicationId=GUID_GOES_HERE
run the workflow and see results.

Expected behavior

No error in the github action.

Screenshots

This value, the output of the script, will be in the subsequent steps, I skip those for clarity. We have two outcomes:

Success:

Failure:

SyntaxError: Invalid or unexpected token

Additional context

My context is, that I am preparing a set of settings for my Application to be deployed in Azure Function App. Those are the settings I will need later. I was adding one after another variables for the app configuration and stumbled on the App Insights connection string.
