When does this happen?

IF Retrieving a dataset via API get_dataset() fails with 404 when the dataset name contains a colon (':').

How others solved it

THEN URL-encode the colon in the dataset name (replace ':' with '%3A') when calling get_dataset(), or upgrade to Langfuse Python SDK v3.0.0+ which handles this automatically.

langfuse.get_dataset('test%3Adata')
