nodebb-plugin-calendar - delete post issue

[JJSagan]

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.
JJ.

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

[JJSagan]

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.

[PitaJ]

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

[JJSagan]

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

[PitaJ]

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

[JJSagan]

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

[PitaJ]

Yes NodeBB works with Node 10

[JJSagan]

Hi @PitaJ

I updated the running environment to Node 10.

>>node -v
v10.11.0

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!
JJ.

[PitaJ]

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

[JJSagan]

Hi @PitaJ

This issue is strange indeed. The documentation for callbackify does not necessitate a callback, see: https://nodejs.org/api/util.html#util_util_callbackify_original

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 "nodebb@github" quality.

JJ.

Fixed in nodebb-plugin-calendar@1.0.0-alpha.43
