When does this happen?

IF API call to retrieve a dataset fails with 404 when dataset name contains special characters like ':'.

How others solved it

THEN Ensure dataset names are URL-safe or encode them before making API calls. Implement URL-encoding for special characters in dataset names when constructing the request URL. Alternatively, validate dataset names to disallow characters that are not valid in URL paths.

import urllib.parse
encoded_name = urllib.parse.quote(dataset_name, safe='')  # encodes special chars like ':'
url = f"{base_url}/api/public/datasets/{encoded_name}"
