Node SDK 3.1.3: Check failed: AllowJavascriptExecution::IsAllowed(isolate)

After upgrading from 3.1.2 to 3.1.3 (but also seen on the 3.2.x betas) we are seeing crashes with the following exception.

This happens both on node:14 and node:16 containers, almost immediately (within a few seconds) in Production, and after a few minutes in QA where traffic is much lower.

We made the upgrade as an attempt to solve the (still unresolved) issues we’ve been facing for nearly 9 months now with libcouchbase crashes (explained here) so maybe those different symptoms could have the same root cause?

@brett19 this sounds like it’s related to the fix for since my research indicates that error often relates to garbage collection?

I’m having the same problem. version 3.2.0-beta.
The issue happens when I run the docker image on but I’m unable to reproduce it when I start the app outside it.

Any idea how to overcome the issue?

This seems to happen with 3.2.0 and CB 7.0 too, also in docker

Hey @Yann_Jouanique ,

This will be fixed in our next release, you can find more details here:

Cheers, Brett
