2. The bug has not been fixed in the latest version.: Yes, the bug is still present in the latest version of the SGLang project.
3. Please note that if the bug-related issue you submitted lacks corresponding environment info and a minimal reproducible demo, it will be challenging for us to reproduce and resolve the issue, reducing the likelihood of receiving feedback.: We have provided the necessary environment info and a minimal reproducible demo to help reproduce and resolve the issue.
4. If the issue you raised is not a bug but a question, please raise a discussion at https://github.com/sgl-project/sglang/discussions/new/choose Otherwise, it will be closed.: This is a bug report, not a question, so we will not raise a discussion.

The bug is related to the served-model-name parameter in the SGLang project. When we set the served-model-name parameter, the model is not loaded correctly, and we encounter an error.

docker run -it --gpus all --shm-size 64g -p 8800:8800  -v /root:/root lmsysorg/sglang:latest python3 -m sglang.launch_server --model /root/models/ --port 8800 --host 0.0.0.0 --served-model-name  DeepSeek-R1-7B

This command will launch the SGLang server with the specified model and port. However, when we try to load the model, we encounter an error.

We are using the latest version of the SGLang project, which is lmsysorg/sglang:latest. We have also provided the necessary environment info, including the Docker image and the command used to reproduce the bug.
