Passing the context of machine in invoke

[gaur23rahul]

Consider the scenario, where I have a state similar to

    send_a_message_W2CuyOyfi: {
      invoke: {
        id: 'send_a_message_W2CuyOyfi',
        src: 'send_message',
       input: {
           'endpoint': 'xxxxxxx',
           'userId': 'xxxxxxx'
       }
        onDone: {
          target: 'ask_a_question_2BkdChpLP',
        },
        onError: {
          target: 'error_handling_w2cuyoyfi',
        },
      },
    },

Now suppose I want to send information from context of current machine to the invoked function which is like

const send_message = fromPromise(async ({ input: { endpoint, userId } }) => {
    await fetch(`${endpoint}/${userId}`);
   return true;
  }),

I want to be able to access data in context of machine in the invoke function. Is that possible and if yes then how. I tried going through docs. In the docs for v5, I didn't see any example/mention of using context in such scenarios. Serialization is my hard requirement. Any help would be really helpful. Thanks in advance.

You can use the function version of input to pass data from context. See the second example here: https://stately.ai/docs/input#invoking-actors-with-input

hey @with-heart ,
Thank for reply but serialization is my hard requirement, and if I put function here, I wont be able to store it in database.

We're still thinking about the best way to serialize selectors, which will help here.
