Firmware Version

2.5.4.8d288d5

Description

Running the library on NodeJS 18.20.5. After a minute or so I keep getting messages about MaxListenersExceededWarning.

It seems to be related to the usage of AbortController() and a bug in NodeJS below version 20. Having a single instance of AbortController that is re-used for all fetch requests will cause the error I'm getting. A workaround would be having a controller on each request and clearing it once it's done its job.
