## Description `jupyter-error-messages` now emits "usage_request" messages. However not all kernels support them, which may lead to error messages in the notebook: ``` ERROR: received unknown message Message type: usage_request ``` See [this discussion](https://matrix.to/#/!bxEXnseMFYzltyRExC:gitter.im/$5NjZDBReRGXYalc03uVvLYZu_nhfpSp5opS78Ibco3k?via=gitter.im&via=matrix.org&via=dendrite.matrix.org) ## Reproduce 1. Install jupyterlab 4.0.4, jupyterlab-resource-usage 1.0.1 and e.g. xeus-cling 0.15.1 from conda-forge. 2. Open a notebook and choose C++ as kernel 3. Run some computations 4. From time to time, the error will appear (sorry, not great in terms of reproducibility :-) ) /cc @jtpio
