Question about lpm match length

I tried to change the stream table in s1-runtime.json to a 16-bit match (which my project will use) in the BASIC exercise, but then it reports an unknown error.
I could achieve this before in the old version of P4 environment, but it doesn’t work in the new one, why is that?


Please do not use an IP address. You can use integers instead of an IP address. Try any numbers without quotes.

For instance,

    "match" : {
        "hdr.ipv4.address" : [45000, 16]


Thank you very much.
