Error fetching data: {e}

Error message

Error fetching data: {e}

What it means

OpenBBError raised in DeribitFuturesInstruments.aextract_data wrapping any exception from the get_instruments('all','future') call. This is a pure transport/wrapper error: get_instruments already converts its own failures to 'Failed to get instruments -> ...', so this fires on network exceptions or unexpected shapes before that mapping.

Solutions

1. Verify network access: curl 'https://www.deribit.com/api/v2/public/get_instruments?currency=any&kind=future' from the same host.
2. Configure proxy/SSL environment variables if the runtime sits behind a corporate proxy.
3. Retry with backoff for transient Deribit outages.
4. Read the inner exception name in '{e}' to distinguish DNS/timeout (network) from other failures.

from openbb_core.provider.utils.errors import OpenBBError
try:
    data = obb.derivatives.futures.instruments(provider="deribit")
except OpenBBError as e:
    if "Error fetching data" in str(e):
        wait_and_retry_once()  # transport-level; usually transient
    raise

When it happens

Trigger: No route to deribit.com, TLS/proxy failures, or an exception raised inside get_instruments outside its try block (e.g. during URL building). Because get_instruments' own errors are re-wrapped here, the message may double-wrap.

Common situations: Corporate proxies blocking deribit.com, air-gapped CI, DNS outages, or Deribit API downtime.
