[BUG] AttributeError: 'BaseModel' object has no attribute 'num_timesteps'

[alicat22]

When queuing the following workflow, I receive an error on the KSampler Adv. (Efficent), AttributeError: 'BaseModel' object has no attribute 'num_timesteps'. Workflow for replication: Bug_Report.json

Expected outcome: The workflow should queue and generate an xy plot with each model located in the folder with 4 seeds.

See below for the error log:

okay will need to review this and update!

[alicat22]

I did some troubleshooting and I figured out what is causing it! If cfg_denoiser is set to True then it produces the above error. If it's set to False then it works correctly.

Hd the same issue and FALSE resolved it, but I figure at the cost of some of the point in that workflow?

[jags111]

I am aware of it and will change part of the code on same so it will resolve
