[Bug]: "Error training embedding Traceback" - when training Embedding or Hypernetwork

[B-Hard]

Is there an existing issue for this?

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

What happened?

When training a hypernetwork with a dataset and Hypernetwork.txt as template, stable diffusion throws the following error: ** Error training embedding Traceback (most recent call last): File "C:\AI\stable-diffusion-webui\modules\textual_inversion\textual_inversion.py", line 593, in train_embedding p.sampler_name = sd_samplers.samplers[preview_sampler_index].name TypeError: list indices must be integers or slices, not str

Training a hypernetwork works fine in v 1.5. This is an v1.6 issue.

Could make it work partly when using this fix: https://github.com/AUTOMATIC1111/stable-diffusion-webui/commit/de5bb4ca88df44362c9263de7334b30156540e21

Also check this previous BUG report https://github.com/AUTOMATIC1111/stable-diffusion-webui/issues/13080

Steps to reproduce the problem

1. Go to Training
2. Press Training hypernetwork with a dataset and some prompt in text2img
3. Press Training Hypernetwork or embedding

What should have happened?

Successfull starting the training/learning process of a given dataset
