GLM 5.3 Flash not receiving arguments or stream ended

Summary

I was trying to find alternative for dsv4f peak hours and I think GLM 5.3 flash is a good model

I was on Go model before, using 5.3 flash with no hassle, both in cmcd, opencode, pi, routed with 9router

Since my Go plan almost ended, I upgraded my plan to GOAT and started using GLM 5.3 Flash.

Weirdly, whenever the model almost reached 100K, It keep getting something like

Validation failed for tool "bash":
   - command: must have required properties command
Received arguments:
 {}

or

Stream ended without finish_reason

I've tried to ask dsv4f to fix this issue, most of the solution says to change the context window to somewhere between 80-90K. The solution sometimes working sometimes not that I reached annoyed state (and moved to dsv4f on peak hours 😭). I believe that this is neither the harness nor 9router's problem (also this is what ds4vf stated too). Just wondering why this happened when I switch plan and it was working fine before

Expected Behavior

GLM 5.3 Flash working fine like a few weeks ago

Actual Behavior

Weirdly, whenever the model almost reached 100K, It keep getting something like

Validation failed for tool "bash":
   - command: must have required properties command
Received arguments:
 {}

or

Stream ended without finish_reason

Steps to reproduce the issue

1. Choose GLM 5.3 Flash as model
2. Produce something with it that it almost reached 80-90K context
3. The Received arguments error will continuously occurred if not auto compact

Additional context

No response

Start by reproducing the issue with GLM 5.3 Flash near the reported 80–100K context range using Command Code 1.44.0 on Linux. Compare the repeated empty bash arguments and missing finish_reason across the reported plan change, and consider the issue done when tool calls receive valid arguments and streams finish normally without requiring auto-compact.
