[Bug]: TypeError: list indices must be integers or slices, not str

[illuculent]

Is there an existing issue for this?

• [X] I have searched the existing issues and checked the recent builds/commits

What happened?

Traceback (most recent call last): File "C:\stable-diffusion\Packages\stable-diffusion-webui\modules\hypernetworks\hypernetwork.py", line 701, in train_hypernetwork p.sampler_name = sd_samplers.samplers[preview_sampler_index].name TypeError: list indices must be integers or slices, not str

Claims this is fixed and closed but I still get this issue. I have the latest update to auto1111. AUTOMATIC1111 deleted the fix-preview-while-generation branch 2 weeks ago. It appears the fix was merged and then deleted so I cannot determine what the fix was. I have tried everything that was suggested within github that I could find to fix this and it is still a no go situation.

Steps to reproduce the problem

click 'Train Hypernetwork' with 'Read parameters (prompt, etc...) from txt2img tab when making previews' checked.

What should have happened?

Trained Hypernetwork

Same here, any workaround? Workaround is to disable Read parameters from img2img checkbox

Where is this in the current branch; I have this same issue, but I can't seem to find a checkbox associated with "Read Parameters"
