Failed to read the 'localStorage'

glebdv · ‎Mar 20, 2019

So I added the script that hubspot provides to the bottom of my body, but in dev and prod I end up getting the following error:

[hub-http] Exception accessing local storage. DOMException: Failed to read the 'localStorage' property from 'Window': Access is denied for this document.

Well, that's kind of a non-answer, as surely one of the points of incognito mode is to block third party cookies and site data.

Incognito mode is a perfectly acceptable way to browse, and it shouldn't raise javascript errors when a conditional could and should be used to check whether a particular library or object is available.

This is fixable, and I'm not sure why it's taking you so long to fix it.

Hi All,

I did some research on this issue today and managed to find what is casing it. I was able to find a similar issue raised on Chromium Projects: https://www.chromium.org/for-testers/bug-reporting-guidelines/uncaught-securityerror-failed-to-read-.... It looks like this might be an issue stemming from your user environment; if the browser is blocking third-party cookies and site data, it would cause an issue. That would explain why we normally can't replicate on our side. Hope this helps!

Same here. Thanks for your research, JVale11. Waiting for a solution.

Same.

Researching the ladder part of the error, I see this is a Chromium seccurity issue:

chromium.org: https://bit.ly/3iRkkne

stackoverflow: https://bit.ly/3gMd35s

Updating settings to "Allow All Cookies" resolves the error. Unfortunately, how users configure their browser is not in our control. Adding a popup that asks users to lower their security settings before entering the website will certainly not inspire confidence. Operating a website with features that may not run correctly due to JS errors is not an operable alternative.

Hubspot, is there a way that the iframe can at least check if localStorage is readable/writable before attempting to read/write to it? And exit before causing a JS error?

This thread was opened in ‎Mar 20, 2019 11:36 AM and still not feedback from Hubspot. Thats poor.

same here incognito mode for me. (Version 89.0.4389.114 (Build officiel) (x86_64))

ZmagoD · ‎Dec 28, 2020

Same here. It happens on Chrome(Version 87.0.4280.88 (Official Build) (x86_64)) incognito mode for me.

Not sure why Hubspot needs the access to localStorage but probably it will be enough to console.warn instead of an error.

This is also happening to me. Only Microsoft Edge (the new chromium version) is showing the error while other browsers are not. Super annoying when having the dev console open trying to develop our web app.

What is HubSpot trying to read from localstorage?

Welcome, @glebdv.

Happy to help. To troubleshoot effectively, though, I'll need a bit more information. Would you:

Define the Hub IDs of the production and developer accounts encountering this issue. Does your production account's ID end in 6807?
Describe your overall goal.
Share "the script that HubSpot provides" and a link to a page where it is installed. Are you referring to the tracking code?

hello, we are facing the same problem. please share the solution with us if possible. thank you

we added the tracking code in WordPress in Astra theme with a custom layout that is a hook and will run on the "astra_content_after" place.

this error occurs on one of our client's browser and in the incognito window of the chrome browser in all pages of our website:
https://zeevou.com

it causes problems in some javascript codes in our pages.

should the tracking code to be added in another specific place in each page?

dennisedson · ‎Oct 20, 2020

hello @yahyamousavi ! I went to the url you have there and am not seeing any errors. Is there a specific method to reproduce the issue or have you resolved it?
