            In PostgreSQL all jsonb array functions only for using JSONB types, not JSONB[].

            1. First-way you can use unnest function to convert arrays to rows, after then you can use jsonb_array_elements.

            2. Second-way change type JSONB[] to JSON in your table. Don't worry, you can still insert your JSON string data which is written above into JSONB field without any problems. Inside the JSON and JSONB strings, we can use arrays using formatted strings. Jsonb array functions only for arrays written inside JSON string.

            From docs:

            An invocation is defined in a state node's configuration with the invoke property

            You are instead trying to invoke in an event node, not a state one.

            I can't speak for the xstate-part, but the last snippet is definitely not working. You can't dynamically declare a tag like this. But you can use the special element for this:

            unable to restore state machine with persisted state using xstate and react
            Asked 2021-Dec-27 at 17:27

            I am trying to create a state machine which can persist the machine's state details at any given point in time and then restore the machine with the persisted state and context values on revisiting the page. The Xstate docs mention about persisting data and rehydration using the local storage but I am unable to do so. I have made a sandbox link to try and replicate the issue. Can someone help or guide me on what I may be doing wrong?

            You must pass the persisted state the first time that you invoke to useMachine, do not forget that useMachine is a closure, in that way it will work, for instance

            Asked 2021-Dec-02 at 18:25

            I have the following React.js component that needs the following:

            • Persist the state when a button is clicked through using fetch to call a server side API.
            • When the component is initialized that the state is set in the component after calling useEffect that uses fetch to call a server side API to get the current state of the object.

            Why this assign does not trigger?
            Asked 2021-Sep-17 at 16:28

            After reading the official xstate tutorial, I tried to implement my own machine inspired by this post on dev.to by one of the xstate's dev.

            Everything works as expected besides that output does not seem to be updated. The assignment does not do its job I think. What did I forget?

            To compare, here is a working demo from xstate where the variable in the context is updated as expected.

            You need to return a Promise then and have the state machine update the context after the Promise is resolved.

            The context is updated in the onDone property of invoke.

            XState doesn't stay in idle state
            Asked 2021-May-27 at 21:33

            I am using xstate together with vuex in my application:

            • vuex handles the user, api calls, response items, etc.
            • xstate handles mainly complex form interactions.

            Due to the reason, that complex forms contain multiple components, which communicate with each other I have to implement xstate not on a component level, but inside vuex. Inside the xstate visualizer it seems to work:

            I can switch between the state, but in the real application it can't go back to its initial state (idle) and then stay there. It always transitions back to the next one. I don't know what I am doing wrong, but I have console logged the formState getter and the output looks like this:
