Error message

\n".join(messages)

What it means

Finviz key metrics fetcher aggregates per-symbol failures: when every requested symbol produced an entry in `messages` (per-symbol errors/warnings collected in get_one) and no results came back, it raises OpenBBError joining all messages with newlines. The joined text identifies which symbols failed and why (usually 'No data found for SYMBOL').

Solutions

  1. Read the joined messages: each line names the failing symbol and reason
  2. Retry with only the symbols that are valid Finviz tickers
  3. Split the batch and process per symbol, skipping failures, if partial data is acceptable

Example fix

# before
res = await obb.equity.fundamental.metrics(provider="finviz", symbol="ZZZZ,YYYY")
# OpenBBError: No data found for ZZZZ\nNo data found for YYYY

# after
res = await obb.equity.fundamental.metrics(provider="finviz", symbol="AAPL,MSFT")
Defensive patterns

Strategy: try-catch

Validate before calling

def split_symbols(raw: str) -> list[str]:
    return [s.strip() for s in raw.split(",") if s.strip()]

symbols = split_symbols(query_symbol)
assert symbols, "symbol list empty"

Try / catch

from openbb_core.app.model.obb_error import OpenBBError

try:
    results = await FinvizKeyMetricsFetcher.transform_query(...)
except OpenBBError as e:
    failed = [ln for ln in str(e).splitlines() if "No data" in ln]
    # drop the named symbols and retry the remainder

Prevention

When it happens

Trigger: Passing a comma-separated symbol list where every ticker fails on Finviz (invalid, delisted, or no metrics row); upstream HTTP errors for each symbol captured into messages.

Common situations: Batch metric pulls over a dirty ticker universe; symbols with exchange-specific spellings Finviz does not accept.
