If you want to remove all occurrences in the list, you can do this:

{
  "script": {
    "lang": "painless",
    "inline": "ctx._source.a.removeAll(Collections.singleton('1'))"
  }
}

or if you want to remove just the first, like this:

{
  "script": {
    "lang": "painless",
    "inline": "ctx._source.a.remove(ctx._source.a.indexOf('1'))"
  }
}

Also note that if you want to use double-quotes, it's fine, but you need to escape them, like ctx._source.a.indexOf(\"1\")).

Or with params:

{
  "script": {
    "lang": "painless",
    "inline": "ctx._source.a.remove(ctx._source.a.indexOf(yourParamName))",
    "params": {
      "yourParamName": "1"
    }
  }
}
