Experiencing Packet Loss on v3 but not v2

but then exits with an error:

Yes it will, it’s an homage to my favourite grumpy programmer:

First f_cnt is empty/null - world wide technical debt in progress

Please be aware that at present the first f_cnt is empty/null aka not 0 so anyone writing any form of integration will need to handle this as any reasonable database should be validating the f_cnt as a number. See First f_cnt is empty/null · Issue #3874 · TheThingsNetwork/lorawan-stack · GitHub

If you want to fix it, I use this in production code:

f_port = theJSON.get(“f_port”, 0)

You’ll need to do the same for any other fields that may return as zero, null, blank or are uninitialised.

In my not very humble opinion it’s a mistake in the design of Google Protocol Buffers translation utilities to JSON that has been perpetuated by programmers half my age because they all think Google has been around forever so much be right whereas I was coding for hire before the web even existed.
