@dosubot[bot] commented on GitHub (Nov 30, 2025):

The error happens because the plugin's requirements.txt does not include the sniffio dependency, but one of its libraries tries to import it, causing the ModuleNotFoundError. This is not addressed in any recent plugin updates or pull requests—sniffio is missing from all versions of the requirements file so far (example).

As a workaround, you can manually add sniffio to the plugin's requirements.txt file (inside models/volcengine_maas/requirements.txt), then rebuild or restart the plugin container so the dependency is installed. For example, add this line:

sniffio

Then restart the plugin daemon. This should resolve the missing module error.

To reply, just mention @dosu.

@bhswallow commented on GitHub (Nov 30, 2025):

thank you!

My temporary solution：
Enter docker-plugin_daemon-1 to find the .venv of the plugin, and install the plugin in .venv. The detailed steps are as follows:
docker exec -it docker-plugin_daemon-1 bash
export LANG=C.UTF-8 LC_ALL=C.UTF-8
export PIP_INDEX_URL=${PIP_INDEX_URL:-https://pypi.tuna.tsinghua.edu.cn/simple}
VENV=$(find /app/storage -maxdepth 5 -type d -name '.venv' | head -n1)
echo "$VENV"
"$VENV/bin/python" -m ensurepip --upgrade || (curl -fsSL https://bootstrap.pypa.io/get-pip.py -o /tmp/get-pip.py && "$VENV/bin/python" /tmp/get-pip.py)
"$VENV/bin/python" -m pip install -U sniffio anyio httpx -i "$PIP_INDEX_URL"
"$VENV/bin/python" -c 'import sniffio,anyio,httpx;print("deps ok")'
exit
docker restart docker-plugin_daemon-1
docker logs -f docker-plugin_daemon-1

#2155 same error, it fixed. you should get the right venv.

不过这个bug好像只在dify 1.10.1上出现，我的环境是dify 1.9.2, 使用volcengine_maas:0.0.33 一切正常。
还是希望官方修正这个bug，否则上面的临时方案一旦volcengine组件升级到0.0.34就要再手动再运行一次。
