When does this happen?

IF Dataset name contains colon character when using get_dataset() API results in 404 error.

How others solved it

THEN URL-encode the colon as %3A in the dataset name when calling get_dataset(), or upgrade to Langfuse Python SDK v3.0.0 which properly handles special characters in dataset names.

langfuse.get_dataset("test%3Adata")  # or upgrade to v3: pip install langfuse>=3.0.0
