Error message

\n".join(messages)

What it means

Finviz price target fetcher mirrors the batch pattern: if every symbol's get_one recorded an error into `messages` and no rows were collected, it raises OpenBBError with all messages joined by newlines. Each message typically says which symbol had no price-target data or failed to fetch.

Solutions

Inspect the joined message lines to see per-symbol failure reasons
Filter the symbol list to tickers with analyst coverage before requesting
Add spacing/retry for rate-limit messages before giving up

Defensive patterns

Strategy: try-catch

Validate before calling

symbols = [s.strip() for s in (query.symbol or "").split(",") if s.strip()]
assert symbols, "price target query needs at least one symbol"

Try / catch

from openbb_core.app.model.obb_error import OpenBBError

try:
    results = await FinvizPriceTargetFetcher.transform_query(...)
except OpenBBError as e:
    bad = {ln.split()[-1] for ln in str(e).splitlines() if ln}
    # retry without `bad`, or record as no-coverage

Prevention

Expect no price targets for tickers without analyst coverage
Respect Finviz rate limits when batching (space requests)
Log per-symbol messages for auditability

When it happens

Trigger: Requesting price targets for symbols Finviz has no analyst coverage for (small caps, OTC); all symbols failing due to rate limiting recorded as messages.

Common situations: Screening pipelines that pull targets for newly listed tickers; batch jobs hitting Finviz rate limits so every request errors.
