This charting method does not support {provider}. Supported

Error message

This charting method does not support {provider}. Supported providers: bls.

What it means

The BLS charting view in economy_views.py only handles Bureau of Labor Statistics response shapes, so it raises RuntimeError when the provider attached to the data is anything other than 'bls'. This mirrors the FRED guard: the downstream pivot logic assumes BLS fields (symbol, date, value) and would mis-render other providers' data.

Solutions

Fetch the data with provider='bls' (e.g. obb.economy.bls.multiple_series(..., provider='bls')) before charting.
For other providers' time series, use the generic charting (to_chart / obb.charting) instead of the BLS-specific view.

Example fix

# before
res = obb.economy.bls.multiple_series(symbols=['LNS14000000'], provider='oecd').charting.bls()

# after
res = obb.economy.bls.multiple_series(symbols=['LNS14000000'], provider='bls').charting.bls()

Defensive patterns

Strategy: validation

Validate before calling

assert kwargs.get('provider', 'bls') == 'bls', (
    'bls chart requires provider="bls"'
)

Try / catch

try:
    fig = res.charting.bls()
except RuntimeError as e:
    if 'does not support' in str(e) and 'bls' in str(e):
        fig = res.charting.to_chart()  # generic fallback
    else:
        raise

Prevention

Fetch BLS series with provider='bls' before calling the BLS chart view.
Use the generic chart route for non-BLS time series.
Make provider an explicit parameter in reusable charting helpers.

When it happens

Trigger: Invoking the BLS charting route (economy_views.py:359, e.g. obb.economy.chart.bls or .charting.bls() on a dataset) with provider='fmp'/'fred'/'yfinance' or with None.

Common situations: Reusing a charting snippet across providers, charting data fetched from a custom provider, or forgetting to set provider='bls' on the data request.
