nodebb-plugin-calendar - delete post issue

  • Hi Devs,
    I am getting the below error on the latest code from github.
    Steps to reproduce -
    create a new topic.
    delete the topic.

    I should say that the forum uses postgres, so that might be related.
    Let me know should you need any more info about this issue.

  • NodeBB Admin

    The stacktrace looks like it might be happening in a plugin, which plugins do you have active?

  • Thank you so much @baris , as usual you guys are right on the money.
    I turned off @Pitaj latest calendar plugin, and the forum is back to normal. The issue seems to stem from deleteEvent.

  • @JJSagan what version of node do you have installed? Try updating to Node 10

  • Hi @PitaJ I am running on node 8.
    Is nodebb compatible with node 10?

  • Latest version of the calendar plugin is only compatible with node 10

  • OK, I'll give it a shot thanks.
    is nodebb forum safe for running with node 10?

  • Yes NodeBB works with Node 10

  • Hi @PitaJ

    I updated the running environment to Node 10.

    >>node -v

    Fresh install of nodebb with nodebb-plugin-calendar.

    Creating a post and then deleting it brings the same issue:

    error:  message=The last argument must be of type Function. Received type object, stack=TypeError [ERR_INVALID_ARG_TYPE]: The last argument must be of type Function. Received type object

    Tracing the code a bit, the issue stems from index.js

    const postDelete = callbackify(deleteEvent);

    Somehow callbackify does not store the callback.

    If I look at the old revision of the code, it used to be:

    const postDelete = (pid, cb) => deleteEvent(pid).asCallback(cb);

    If I use the old code above, deleteEvent does get called properly, but falls on promise issue.
    Seems that deleteEvent does not have a callback in its arguments, so that may be the issue.

    Any idea how to resolve?
    Thank you!

  • Yeah it appears my post delete hook handler is wrong. Can you open an issue on the repository? I'll try fixing it soon.

  • Hi @PitaJ

    This issue is strange indeed. The documentation for callbackify does not necessitate a callback, see:

    However, callbackify fails if not provided with a callback 😞

    So first, I tried:

    const postDelete = (pid, cb) => callbackify(deleteEvent)(pid, cb);

    However, since "action:XXX.YYY" does not have a callback to begin with, cb is undefined, thus callbackify fails.

    So finally I used an empty callback function:

    const postDelete = (pid) => {
       callbackify(deleteEvent)(pid, function () {} );

    Its a working solution but I feel somewhat uncomfortable with it.
    Pretty sure its NOT "[email protected]" quality.
