Web site throwing "Culture is not supported" error and stops working

[aseedig]

Description

When working on an analytics dashboard website and try to export data to excel, the server responds with the following error:
"There was an error while processing your request.
The error was: Culture is not supported. Parameter name: name en-GB;q=0.8 is an invalid culture identifier."

It seems that the Language settings is adding the following parameters to the Request Header: "name en-GB;q=0.8"
This was working in previous Brave versions and I discovered this issue since Brave Version v1.42.86

Steps to Reproduce

You would need access to the application to reproduce the issue. However, the Request Header contains the above mentioned parameter and this needs to be addressed. I might be able to grant access to an export function for trouble shooting purposes, but cannot give access here to the restricted internal application. This export function is working with:

• Chrome Version 104.0.5112.79 (Official Build) (x86_64)
• MS Edge: Version 104.0.1293.47 (Official build) (x86_64)

Actual result:

Expected result:

Reproduces how often:

Easily reproducible... Just need access to the export function.

@aseedig Do you have a pointer to the website/app where you're seeing this error?

[aseedig]

Not yet, but can produce something shortly. As mentioned, this is an internal analytics dashboard of an insurance company and I cannot share the data in the public. I can however make a test page accessible for testing and reproduction. Just wanted to know that someone is picking it up.

Please and thank you.

Hey guys,

please us the following URL for testing:
https://manager.hampshire4x4response.net/Application/rdPage.aspx?rdReport=ExportTest

Please let me know if you need anything else.

I have set the debug mode to on, so you will see a lot of details in the data. but nothing points to the error apart the message that the Culture is not supported:
[Culture is not supported. Parameter name: name en-GB;q=0.9 is an invalid culture identifier.]

Disable Shields Up and the export works.

Thanks

Axel

[pilgrim-brave]

Thank you. I confirmed the bug and also confirmed that it is fixed already in nightly builds by brave/brave-core#14338.

[pilgrim-brave]

Thanks very much for the bug report. As I mentioned, it's fixed in nightly and so will be made available on all platforms shortly, in version 1.44. In the meantime, you can work around it by going into the shields panel, under Advanced Controls, change "Block fingerprinting" to "Allow fingerprinting" for this site. (You don't need to disable "Shields Up" entirely.)

Thank you very much for taking the time to report the bug and helping us get this sorted; it's greatly appreciated. I am checking if there is anything i can do to get to fix shipped faster, but worst case know it'll be in version 1.44.

[aseedig]

Great news. Thank you for taking this on and resolve it so quickly.
Great work.

Hi Stephen, Thank you for the info. The exception is because the test page doesn’t log in to the system and the Logo is based on the customer ID. Hence the Link to the JPG file is incomplete and triggers the exception. Nothing to do with the actual report, just a cosmetic issue not showing the customer logo. Thanks again for your help.
