Error message

No data found.

What it means

EmptyDataError raised in IntrinioEtfSearchFetcher.transform_data when the fetched data list is empty before DataFrame conversion. This fires when the fetcher returned nothing at all — distinct from the post-filter case, since the regex name filter is applied after this check.

Solutions

1. Broaden the search term (e.g. 'tech' instead of 'semiconductor leverage')
2. Search by issuer or well-known fund names; drop the query parameter to list ETFs
3. Catch EmptyDataError and show 'no ETFs matched' in the UI rather than an error

Example fix

# before
res = obb.etf.search(provider="intrinio", query="quantum computing leverage")

# after
res = obb.etf.search(provider="intrinio", query="quantum")

def query_broad_enough(q: str, min_len: int = 3) -> bool:
    return len((q or "").strip()) >= min_len

from openbb_core.provider.utils.errors import EmptyDataError

from openbb_core.provider.utils.errors import EmptyDataError

try:
    res = await obb.etf.search(provider="intrinio", query=q)
except EmptyDataError:
    res = await obb.etf.search(provider="intrinio", query=q[:4])  # broaden term

When it happens

Trigger: ETF search where Intrinio returns no 'etfs' array (or an empty one) for the request: searches with zero hits, or responses where only a 'messages' key was present but empty enough not to raise error 672. Also raised when the fallback unfiltered call returned nothing.

Common situations: Searching obscure terms with no ETF matches; regional/language-specific queries; API returning empty results during degraded service.
