Hello Everyone, I am getting error Unable to regenerate API key. Invalid password

For Workers & Pages, what is the name of the domain?
NA

What is the error number?
1071

What is the error message?
Unable to regenerate API key. Invalid password

What is the issue or error you’re encountering
Trying to get the global API to work with the Cloudflare API, but while clicking on view, it asks for the password, which I don’t have, as I have logged in using Google auth

What steps have you taken to resolve the issue?
I tried adding the custom API as a password at that time, but it started giving this error.

Chaika•5/2/25, 4:45 PM

You can logout and use the "Forgot your password?" option on the login screen, to get it set and then generate it
Using Global API Key isn't recommended though, scoped api tokens are more secure

camden•5/2/25, 10:56 PM

hey, any idea how the caching works for the REST API? IE: If I do a call to /markdown/markdown, then immediately after do a /scrape/scrape call to get the title element, will that generally have to re-scrape or can it pull from the cache?

hey, Kathy, this issue has not been fixed yet. I think it is a bug obviously, when will your team fix this.

camden•5/5/25, 6:16 PM

hey guys, your docs are messed up for the scrape endpoint. https://developers.cloudflare.com/api/resources/browser_rendering/subresources/scrape/

The result shape is {result: [{ results: [{ ... }] }]}{result: [{ results: [{ ... }] }]} not {result: {result: {}}}{result: {result: {}}}

Another serious issue. Links endpoint works with

url

url

, but pass in the htmlhtml provided from /content/content of scraping that url and it doesn't work

camden•5/5/25, 6:50 PM

Another thing... I would really like to be able to get the title of the page, I'm not sure if scraping for the title element will be good enough for SPAs... I tried to do this by injecting a script that would create a new dom element with document.title content in it but that didn't seem to work.

Hi, I am evaluating browser rendering API for an AI agent with browsing capability and persistent session (logged in user). Is this a good solution? (I also looking at Browserbase)

KKathy thanks for raising these bugs + feature request.

camden•5/7/25, 4:19 PM

I'm receiving a ton of 429s, any chance I can get some help raising the rate limits? I'm happy to do a user interview call too with our use cases or if you're thinking through pricing

rufi•5/9/25, 3:09 PM

hello
We have a issue with puppeteer setUserAgent
we do a classical await page.setUserAgent(userAgent);
but the navigator.userAgent always returns Cloudflare-Workers, ignoring what we used. Is that expected, a known issue or something?
This is blocking us for leveraging the browser api properly since sites we analyze recognize this fact and respond differently.

SS0ns0fAnarchy did you figure this out?

confusionprevails•5/27/25, 1:58 PM

Nope! Moved away from using CF rendering.

highvoltage•5/29/25, 11:24 PM

Hey CF team. I'm having trouble using the Browser Rendering binding in one of my workers to render a PDF of a web page. This was previously working ealier this month, but now the page.createPDFStream method is not returning a stream. Using page.pdf returns "Cannot create buffer". Any ideas on what would cause this?

Razmjoo•6/3/25, 3:47 PM

Hello everyone, what is the best way to increase the rate limit on the browser rendering rest api? My account is set to startup/enterprise, so I assume it is configured to the default (60 r/min). We don't use this API constantly; however, when we do, we will have spikes in our usage for a short time, then it drops back to zero (it might increase later on) (unfortunately, our workflow is triggered by demand, and we can't schedule them in advance).

Kathy•6/3/25, 8:47 PM

if you are on a paid plan, you can request higher limits here https://developers.cloudflare.com/browser-rendering/platform/limits/#workers-paid.

we ask that you only submit reqest if you're actively hitting limits as increasing limits requires manual action at this time and we want to prioritize customers who truly need the additional capacity. We're working on raising limits for everyone across the board, so this will become less of an issue in the future

Marco Aleixo•6/5/25, 10:13 PM

hey team - do you plan to remove this limitation?

Browser Rendering is not supported locally. Please use `wrangler dev --remote` instead.

rodders1013•6/15/25, 11:38 AM

Very quick question before I spend sometime looking into this, I generate images from my worker app as react components, css/html. I’m using puppeteer to take screenshots of the component and turn them into .png. Can I incorporate this instead of puppeteer? Or is it as well as puppeteer?

are there known issues with font rendering using browser rendering in a worker? this works locally b
