Your current environment

I encountered an issue where the service returns a 502 error whenever the content field in the request includes certain CLI commands.

The model service is deployed using the Docker image vllm/vllm-openai:v0.11.2

Before submitting a new issue...

  • Make sure you already searched for relevant issues, and asked the chatbot living at the bottom right corner of the documentation page, which can answer lots of frequently asked questions.

extent analysis

TL;DR

The issue may be resolved by updating the Docker image to a version that handles CLI commands in the content field correctly or by sanitizing the input to prevent malicious commands.

Guidance

  • Verify that the issue is specific to the vllm/vllm-openai:v0.11.2 Docker image by checking if other versions exhibit the same behavior.
  • Check the documentation for any known issues or workarounds related to CLI commands in the content field.
  • Consider sanitizing the input to the content field to prevent any malicious CLI commands from being executed.
  • If possible, test the service with a different input that does not include CLI commands to isolate the issue.

Notes

The exact cause of the issue is unclear, and more information about the service and its configuration may be needed to provide a definitive solution.

Recommendation

Apply workaround: Sanitize the input to the content field to prevent malicious CLI commands, as this is a safer and more immediate solution than updating the Docker image without knowing the specific changes in newer versions.
