I have provided every relevant configuration, setting, and environment variable used in my setup.
I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:

🟣 #24575 bug: 'NoneType' object has no attribute 'startswith' on /api/chat/completions when external client omits parent_id
This is the closest match: it reports the same 400 error with 'NoneType' object has no attribute 'startswith' on /api/chat/completions for external OpenAI-compatible clients, specifically when required context like parent_id is missing. The reported OpenCode failure in #24603 is the same symptom and likely the same request-path regression.

🟣 #24550 bug: NoneType object has no attribute 'startswith' — all /api/v1/chat/completions calls return 400 (v0.9.5, direct connections)
This issue describes the same 'NoneType' object has no attribute 'startswith' 400 error for external completions API clients, including OpenClaude CLI and VS Code extensions. It appears to be the broader underlying bug affecting external API requests, which would include OpenCode.

🟣 #24573 issue: External API returns 400 error with 'NoneType' object has no attribute 'startswith' since v0.9.3**
This earlier report matches the same error message and the same external API /api/chat/completions path across v0.9.3+ versions. It provides historical context that the regression affects token-authenticated external clients, which is consistent with the OpenCode breakage in #24603.

🟣 #24554 issue: Open WebUI v0.9.5 Broken Completions API
This issue reports the completions API breaking in v0.9.5 specifically for OpenCode and Continue Dev, with the same 'NoneType' object has no attribute 'startswith' error. Since #24603 is also about OpenCode over the API and the error persists in a later version, it is directly related.
