Seedance 2.0 Extend & Omni endpoint issues

[Mojage-create]

Environment

• ComfyUI v0.16.4
• muapi-comfyui (latest)
• macOS / Apple Silicon

Issue 1: seedance-v2.0-extend always fails with "parent task expired"

After successfully generating a video with seedance-v2.0-i2v, I immediately chain it to seedance-v2.0-extend using the request_id output. The I2V completes successfully, but the Extend always fails with:

failed to get parent task runtime, please check if the parent task expired

This happens even when both nodes run in sequence within the same ComfyUI execution (no manual delay between them).

Questions:

1. Can seedance-v2.0-extend use request_ids from seedance-v2.0-i2v?
2. How long is a parent task's request_id valid before it expires?
3. Does the Extend endpoint support the remove_watermark parameter in extra_params_json? (I'm passing {"remove_watermark": true})

Issue 2: seedance-2.0-new-omni always fails with "Insufficient credits"

Every request to seedance-2.0-new-omni fails with:

Insufficient credits: requires at least 10.0 credits, current balance: -24.0 credits

My account balance is $48+ (confirmed on dashboard). The seedance-v2.0-i2v and seedance-v2.0-t2v endpoints work fine with the same API key.

Questions:

1. Is seedance-2.0-new-omni fully available, or is it still in preview/beta?
2. Is there a separate credit system for omni endpoints?
3. How can I resolve the negative credit balance shown in the error?

Dashboard screenshot context

• Total requests: 5
• seedance-2.0-new-omni: 3 requests, $0.00 (all failed)
• seedance-v2.0-i2v: 1 request, $1.25 (success)
• seedance-v2.0-t2v: 1 request, $0.60 (success)

Thanks for your help!

Can you try again, we have updated with new omni nodes which should be working now. Also added few more additional endpoints for Seedance 2 like 480p endpoints
