Bug

Every call to github-copilot/claude-haiku-4.5 fails with a 400 schema rejection, causing an immediate fallback to the next model in the chain. This is 100% reproducible — not intermittent.

Observed 33 failures today alone across all heartbeat runs (main, subconscious). The eager_input_streaming field appears to be included in the tool definition sent to the Copilot endpoint, which rejects it as an extra/unknown field.

Impact

All heartbeats configured with github-copilot/claude-haiku-4.5 silently fall back to anthropic/claude-sonnet-4-6 (paid) on every single run. This has been causing unexpected Anthropic billing.

Environment

  • OpenClaw: 2026.4.22
  • Provider: github-copilot (plugin)
  • Model: claude-haiku-4.5
  • OS: Linux 6.8.0-110-generic x64
  • Node: v22.22.1

extent analysis

TL;DR

Remove the eager_input_streaming field from the tool definition sent to the Copilot endpoint to resolve the 400 schema rejection error.

Guidance

  • Verify that the eager_input_streaming field is indeed being sent in the request payload by checking the tool definition configuration.
  • Check the Copilot endpoint documentation to confirm that the eager_input_streaming field is not a supported or required field.
  • Update the tool definition to exclude the eager_input_streaming field and test the request again to see if the error is resolved.
  • Monitor the heartbeat runs to ensure that the fallback to the paid Anthropic model is no longer occurring.

Example

No code snippet is provided as the issue is related to a specific field in the tool definition, which is not shown in the provided information.

Notes

The solution assumes that the eager_input_streaming field is not required for the Copilot endpoint. If this field is necessary, further investigation into why it's being rejected as an extra input will be needed.

Recommendation

Apply workaround: Remove the eager_input_streaming field from the tool definition, as it is likely causing the schema rejection error and resulting in unexpected Anthropic billing.
