How to send Post request in Github Actions under Windows?

I need to notify Sentry about new build version when CI made it. I am using runs-on: windows-latest for builds and sending requests with a code below:

- name: Notify Sentry
run: |
  $VERSION_NAME = "${{  github.ref_name }}"
  $REQUEST = "{`"version`": `"$VERSION_NAME`"}"
  echo $REQUEST
  curl -X POST -H "Content-Type:application/json" -d "$REQUEST" "https://sentry.io/api/hooks/release/builtin/...id.../...token.../"

Request looks correct, but it always returns error Expecting property name enclosed in double quotes:

Run $VERSION_NAME = "${{  github.ref_name }}"
  $VERSION_NAME = "${{  github.ref_name }}"
  $REQUEST = "{`"version`": `"$VERSION_NAME`"}"
  echo $REQUEST
  curl -X POST -H "Content-Type:application/json" -d "$REQUEST" "https://sentry.io/api/hooks/release/builtin/...id.../...token.../"
  shell: C:\Program Files\PowerShell\pwsh.EXE -command ". '{0}'"
  
{"version": "v1.1.1"}
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

{"error":"Expecting property name enclosed in double quotes: line 1 column 2 (char 1)"}

In Postman it works well. How to fix this error?

Use backslash instead of backtick to escape nested double quotes.

Change this:

$REQUEST = "{`"version`": `"$VERSION_NAME`"}"

to:

$REQUEST = "{\"version\": \"$VERSION_NAME\"}"

You may use single quotes instead of nested double ones and then use Replace function to bulk escape those like this:

$REQUEST = "{'version': '$VERSION_NAME'}".Replace("'",'\"')
