No data was returned for any symbol

Error message

No data was returned for any symbol

What it means

Finviz price target raises EmptyDataError('No data was returned for any symbol') when the loop over symbols produced zero rows and no error messages were collected. Distinguished from the OpenBBError variant: here symbols were accepted but returned nothing, so there is nothing to report.

Solutions

1. Ensure a non-empty symbol string is supplied
2. Verify coverage with a single symbol request before batching
3. Treat EmptyDataError as expected for coverage-less tickers

Example fix

# before
await obb.equity.price_target(provider="finviz", symbol="")  # EmptyDataError

# after
await obb.equity.price_target(provider="finviz", symbol="AAPL")

assert query.symbol and query.symbol.strip(), "symbol is required for finviz price targets"

from openbb_core.provider.abstract.errors import EmptyDataError

try:
    res = await obb.equity.price_target(provider="finviz", symbol=sym)
except EmptyDataError:
    res = []  # no coverage for these tickers

When it happens

Trigger: Symbols with no analyst price targets on Finviz; an empty symbol string (query.symbol falsy gives an empty list and immediate EmptyDataError).

Common situations: Passing symbol='' or None through a template; illiquid tickers without analyst coverage.
