Can't add or edit Autorecs in Firefox or Safari, why?

downbythestream

We just recently installed HTS Tvheadend 4.3-2375~g653bd0400 using a Docker container, and we moved some configuration settings from a previous installation as we have done several times in the past, and after a few minor hiccups it all seems to work, except that today we found that we cannot add or edit an Autorec entry. If we click either the "Add" or "Edit" buttons, a box very briefly appears on the screen that says "Loading, please wait" and then it just disappears and the dialog box that lets you add or edit an entry in the Autorecs list never appears. This does not appear to be an issue in any other part of the Tvheadend interface, but it is problem when using Firefox under MacOS or Ubuntu Linux, or Safari under MacOS. Strangely, in Ungoogled Chromium running on Ubuntu 24.04 the dialog boxes DO appear. We didn't have time to experiment any more than that tonight (and don't use Windows at all, so can't say what happens there), but I just wanted to try to find out if anyone knows why we are seeing this weird behavior and if there is any fix for it.

Works fine in Firefox on my Mac, although I'm on an older release.

Open the Web Developer Tools in Firefox, open its Network tab, and then attempt the autorec actions again. Every attempt to open the autorec dialog should make a successful (status 200 OK) POST to api/dvr/autorec/class -- if it doesn't, note what the status is and also check the Console tab of the Web Developer Tools for any relevant messages.

You could also do the same with the developer tools in Chrome and compare.

Tony Wagner In the Networks tab when I click Add it makes several; requests, all of which show the status of 200 in a green button, which I assume means OK. In the Console tab there is one error: "Uncaught TypeError: r.get(...) is not a string" (with "tvh.js.gz:243:247" at the end of the line) and at the bottom of the window there is a link to https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/Unexpected_type, If I highlight and existing Autorec and click Edit pretty much the same thing happens, except in the Console tab I see two additional unusual items:

Source map error: NetworkError when attempting to fetch resource.
Resource URL: moz-extension://60602632-500e-40d3-8751-ae93948bb2ed/browser-polyfill.min.js
Source Map URL: browser-polyfill.min.js.map

Request for font "SF Pro Display" blocked at visibility level 2 (requires 3)
(with "utils.js:107:48" at the end of the line)

This is in standard Firefox version 134.0.1. And as I said all other Add or Edit dialogs I have tried seem to come up, it is just the Autorecs that have this issue.

In Ungoogled Chromium Version 131.0.6778.264 (Official Build, ungoogled-chromium) (64-bit) it's basically "nothing to see here", there are no errors or warnings in the Network tab, and the Console tab shows nothing at all when I click the Add or Edit button.

downbythestream This seems to be a known problem with a pending PR solution - see https://github.com/tvheadend/tvheadend/pull/1786. I don't know why it hasn't been applied, probably @Flole is busy.

davep Thanks, that definitely seems to be the issue. I just installed Vivaldi and tested in that, and the "Add" and "Edit" buttons work there as well. So, currently it is only Firefox and Safari that seem to have the problem. Really hope that fix gets applied soon.
