No training items found in the dataset

feature-wan-2-2 branch. It founds images but shows dataset error.

dataset file:

[general]
resolution = [960, 960]
caption_extension = ".txt"
batch_size = 1
enable_bucket = true
bucket_no_upscale = false

[[datasets]]
image_directory = "/workspace/musubi-tuner/dataset"
cache_directory = "/workspace/musubi-tuner/dataset/cache"
num_repeats = 1 # optional, default is 1. Number of times to repeat the dataset. Useful to balance the multiple datasets with different sizes.

Error itself:

Maybe the cache doesn't exist. Please run wan_cache_latents.py and wan_cache_text_encoder_outputs.py before training.
