What is causing the error message "POST https://rum-http-intake.logs.datadoghq.com/v1/input/pub9238a331d14b5f49624bb5e93b1bbd64?ddsource=browser&ddtags=sdk_version%3A3.6.12%2Cenv%3Aprod%2Cservice%3AWebflow-Dashboard%2Cversion%3Amain-7aa45cc013078e2b9def076ddf9bb0d99acbf3a5&batch_time=1687869247112 net::ERR_BLOCKED_BY_CLIENT" when trying to edit a component in Webflow that contains an embed element?
TL;DR
- The error is caused by a browser extension (like an ad blocker) blocking telemetry requests to DataDog, not by an issue in Webflow or your code.
- Disable extensions, whitelist Webflow/DataDog URLs, or use an incognito window to prevent the error without affecting functionality.
The error message net::ERRBLOCKEDBY_CLIENT while editing a component in Webflow that includes an embed element is typically caused by a browser extension blocking a request, not by an issue in Webflow or your project’s code.
1. Understand the Error Source
- "POST https://rum-http-intake.logs.datadoghq.com..." refers to DataDog RUM (Real User Monitoring), a third-party analytics service used by Webflow to track performance and behavior.
- "ERRBLOCKEDBY_CLIENT" is a Chrome and Chromium-based browser error that means a browser extension (usually an ad blocker or privacy tool) has blocked the network request.
- This doesn’t affect the functionality of your component — it only blocks requests being sent from the dashboard to DataDog.
2. Common Extensions That Cause This
- Ad blockers like uBlock Origin, Adblock Plus
- Privacy tools like Ghostery or Privacy Badger
- Firewall-based extensions like Malwarebytes Browser Guard
These tools block known tracking and telemetry domains — like logs.datadoghq.com.
3. How to Fix or Avoid It
- Temporarily disable browser extensions while editing your project in Webflow, especially ad blockers.
- Whitelist Webflow and DataDog URLs in your ad blocker or privacy extension settings if disabling is not an option.
- Alternatively, use an incognito window without extensions or another browser to edit Webflow without interference.
4. Impact of the Error in Webflow
- The error does not prevent proper functioning of the embed element or your components.
- It only blocks telemetry data from being sent by your Webflow Designer or Dashboard to DataDog.
- You can safely ignore it unless you are troubleshooting issues related to Webflow performance monitoring.
Summary
The error net::ERRBLOCKEDBY_CLIENT is caused by a browser extension—most likely an ad blocker—preventing Webflow from sending telemetry data to DataDog. Disable or whitelist the extension to eliminate the error, though it does not impact your embedded elements or site functionality.
