Facebook treats verify tokens as case-sensitive strings. Double-check that the token in your n8n webhook node exactly matches the one you entered in the Facebook Developer Portal, including capitalization, numbers, and special characters.

A particularly vexing issue for n8n Cloud users is the problem. In some instances, the n8n Cloud instance may be running an outdated version where the OAuth2 credential flow for Facebook (which allows for automatic token refreshes) is absent, replaced by a manual "Access Token" field. This forces users to manually generate a token every two months, creating a maintenance burden. The solution, in this case, is to contact n8n support to have your cloud instance updated to a modern version.

Here is a draft blog post with some general information, please let me know if you want me to change or add anything:

If the Hermes engine runs out of memory or hits an infinite recursion loop within a fast-executed callback (like gesture responders or navigation events), it will throw a JSI exception. n8facebook3jsi7jserrore best

However, the Reanimated library relies heavily on a specific JSI component known as WithRuntimeDecorator . This decorator is responsible for ensuring "non-concurrent access" to the runtime. In versions of React Native prior to 0.75, the WithRuntimeDecorator implementation had a fundamental flaw: it lacked several critical methods required for safe memory management when multiple threads attempted to access the same JavaScript runtime simultaneously.

While the N8facebook3jsi7JSErrorE is a specific bug, preventing similar issues requires adopting a broader discipline in React Native development.

Ensure that all libraries using JSI (like react-native-gesture-handler or bottom-sheet ) are compatible with your current version of reanimated . 3. Debugging Production Crashes
