[BUG] InfiniStore returns `Unexpected opcode: 129`

[HonkitMaiStorage]

Describe the bug
After setting up the InfiniStore server, I tried to run the infinistore/example/client.py to test whether the setup is successful. Then, the error encountered here is

[2026-01-08: 10:08:18.897] [infini] [info] Connecting to <server-ip>

The script above is run on the same node as the InfiniStore server, meaning the server-ip is actually the localhost IP. Then, to verify the RDMA connection is successful, ib_write_bw is also run and the benchmark results has the appropriate output as well. Therefore, the RDMA connection does not have any issue.

After the client has completed the request, the server log may/may not show the following log (Invalid header)

To Reproduce

Install the InfiniStore by building from source

apt install libuv1-dev
apt install libflatbuffers-dev
apt install libspdlog-dev libfmt-dev
apt install ibverbs-utils libibverbs-dev
apt install libboost-dev libboost-stacktrace-dev
pip install --no-build-isolation -e .
pip install pre-commit
pre-commit install

Then, set up the InfiniStore server using

infinistore --manage-port 8088 --service-port 12345 --dev-name irdma0 --hint-gid-index 1 --link-type Ethernet --prealloc-size 2

Afterwards, run the test script provided in this repository after pointing the IP to the correct IP Address.

python3 infinistore/example/client.py
