Web/Desktop App: Submit/Cancel button in interactive dialog sometimes does not populate channel_id

https://github.com/mattermost/mattermost/issues/23754

Summary

Mattermost Web/Desktop client sometimes does not populate channel_id field in /dialog/submit a request when clicking on Submit/Cancel button in the interactive dialog.

Steps to reproduce

Open an interactive dialog. Open the browser console (in Chrome: Press F12, Network) Click on the Submit/Cancel button. Check in the console if the channel_id is correctly populated in the request body of /dialog/submit.

Expected behavior

When clicking on the Submit/Cancel button in an interactive dialog, the Mattermost web client sometimes does not populate the channel_id in the /dialog/submit request body. As a result, the Mattermost server responds with a 403 error. Occasionally, opening the post/thread link from which the dialog is invoked in a separate window resolves the issue. This bug has been observed on both Windows/Chrome and Mac/Safari platforms. No such errors have been noticed in the Mattermost mobile app.

Mattermost Version: 7.10.2 Mattermost Desktop Version: 5.3.1 2c3d80f Chrome Version: 114.0.5735.133 Safari Version: 16.5 (18615.2.9.11.4)

Observed behavior

Request from Mattermost Web Client (Chrome - F12 - Network): POST https://mattermost-test.skyeng.tech/api/v4/actions/dialogs/submit Request body: {{{ "url":"http://sel-tezis-test.skyeng.link:8888/mattermost/webhook/assignment/confirm", "callbackid":"", "state":"...", "submission":{ "comment":null }, "channel_id":"", "teamid":"qy68iknxw7bopqqn1bbkswr4yy" }}} Response: { "id":"api.context.permissions.app*error", "message":"You do not have the appropriate permissions.", "detailed_error":"", "request_id":"bdndggffnfdc9ggngs7xoej7xc", "status*code":403 }
