# Trying to access /tags gives an error due to keyword conflict **URL:** \ **Category:** Bug\ **Created:** [August 15, 2020, 4:33am UTC](https://meta.discourse.org/t/trying-to-access-tags-gives-an-error-due-to-keyword-conflict/160953 "2020-08-15T04:33:36Z")\ **Posts on this page:** 6\ **Page:** 1 ## AI-generated summary Users reported an error when accessing `/tags` on the Discourse site, despite individual tag pages working fine. Initial troubleshooting by [Stranik](/t/-/160953/2) and [neounix](/t/-/160953/4) suggested possible plugin or JS conflicts, but [looeee](/t/-/160953/1) confirmed minimal plugins and themes were in use. The root cause was identified by [j.jaffeux](/t/-/160953/5) as a JavaScript keyword conflict: the tag named `constructor` triggered unexpected behavior because `obj['constructor']` returns the object’s constructor method instead of `undefined`. Renaming or deleting the `constructor` tag resolved the issue. [looeee](/t/-/160953/6) confirmed the fix and noted a related usability concern: editing tags on old posts bumps them to the top of the feed, disrupting active discussions. They asked if admins can edit tags without affecting post visibility or sorting — a feature request implied but not addressed in the thread.

When I try to access `https://discourse.threejs.org/tags` I get an error: ![err](https://global.discourse-cdn.com/meta/original/3X/f/e/feb975717aeaee9777cdd660c69bc58c8b6d43e3.png) However, tags are enabled and working, and I can access individual tags like `https://discourse.threejs.org/tag/geometry` without problems. Does anyone know what’s going on here? Have I disabled the tags page by mistake somehow? ---

Are there any addons or plugins worth you? On the tags page (in the browser) you have a lot of errors. `TypeError: o.setProperties is not a function...` `Error while processing route: tags.index o.setProperties is not a function TypeError: o.setProperties is not a function` The situation persists with `safe-mode`. I updated my instance a minute ago and there are no errors. Perhaps some extensions (plugins) are interfering? ---

We’re using the open source community version, so we’re pretty limited in terms of plugins. Here’s what the plugins page looks like: ![err2](https://global.discourse-cdn.com/meta/original/3X/5/7/57bfbeff28c6522462f19eeeeae8566a6e031536.png) I’ve installed some themes and a couple of components too: ![themes](https://global.discourse-cdn.com/meta/original/3X/b/0/b01fb24f861d07104973f859870e504348f0fb6d.png) ![comp](https://global.discourse-cdn.com/meta/original/3X/6/c/6c122ab05866ce0607741902bcd1da0e2b74c448.png) However, I tried disabling the components and updating the themes but it doesn’t change anything. ---

Hey @looeee Sorry to read you are having this issue. I visited your site and took a quick look for you and found a lot of javascript errors in the console; but I could not trace the console error to a specific main line in the Ember / JS code. To confirm it was related to javascript, which is easy enough to do, I looked at your site (the tags page) with the user agent set to GoogleBot, and could access the page: ![Screen Shot 2020-08-15 at 5.15.49 PM](https://global.discourse-cdn.com/meta/original/3X/a/3/a3191244bbe89b8b05ea2397945f8f7e66c655d2.jpeg) Here is a “long shot”, “just to see” kinda thing, but it might lead you to some clues. Consider temporarily “disabling tags” in your admin panel settings: ![Screen Shot 2020-08-15 at 5.28.30 PM](https://global.discourse-cdn.com/meta/original/3X/8/2/82919db580d108e555807ccc8f9283158331a4d9.jpeg) Then navigate to your tags page like before and refresh. You should get the standard Discourse 404 error: - Oops! That page doesn’t exist or is private. If you do not see the ’ Oops! That page doesn’t exist or is private’ message after you disable thread tags, that will be an interesting surprise; but I guess you will. Then, go back into your admin settings and re-enable your thread tags, and refresh the tags page again. I am guessing you will still see the “Something went wrong” message, but it is easy enough to disable and re-enable, and see if anything new or interesting appears which might be a clue. HTH. ---

Hello @looeee, You are running into a rare issue due to one of your tags `constructor` and some JS code. I will get a fix Monday, in the mean time if it’s urgent to you, you can rename the constructor tag to something else, or delete it. /tags/constructor should be accessible. * * * For a longer and more nerdy story, at some place in code we do something like: ```plaintext const obj = {}; obj['constructor'] ``` And instead of returning undefined, it actually returns the constructor method of the object [Object.prototype.constructor - JavaScript | MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/constructor) which is obviously something our code wasn’t expecting 😅 ---

> [@j.jaffeux](#): > > And instead of returning undefined, it actually returns the constructor method of the object Doh! Haha, can’t say I haven’t done similar things before. Thanks for digging into this for me. It looks like “constructor” was a mispelling in any case - it was supposed to be “construction”. It was only on one post so I have removed it and sure enough the /tags page is working again. Thanks for the speedy help, much appreciated 🙂 EDIT: now that I can access the tags again, I want to tidy them up and consolidate them. However, I’m reminded why I never do this. As soon as I edit the tags on a post, even one that’s several years old, it gets bumped back to the top of the list. If I batch edit lots of tags at once, which I want to do every few months, this completely disrupts all active discussions as they get buried under the re-tagged posts. Is there any way that I, as site admin, can edit tags or otherwise edit a post affecting it’s place in the list?
