This charting method does not support {provider}. Supported

Error message

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

What it means

The FRED dataset charting view (economy_views.py) is hard-wired to FRED data shapes, so it refuses any provider other than 'fred'. kwargs carries the provider used for the data request; if it is anything else (or None with injected data), the view raises RuntimeError immediately rather than producing a malformed multi-series chart.

Solutions

Fetch the series with provider='fred' before invoking this chart: obb.economy.fred.series(symbol, provider='fred').charting(...).
For non-FRED time series, use the generic chart endpoints (obb.economy.chart or to_chart on the OBBject) instead of the FRED-specific view.
If injecting your own DataFrame, accept that this method is FRED-only and pick the generic line chart.

Example fix

# before
res = obb.economy.fred.series('T10YIE', provider='oecd').charting.to_chart()  # wrong chart route

# after
res = obb.economy.fred.series('T10YIE', provider='fred').charting.fred()

Defensive patterns

Strategy: validation

Validate before calling

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

Try / catch

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

Prevention

Match chart method to the provider used on the data request.
Default to the generic to_chart() for cross-provider workflows.
Keep provider explicit (not inherited from a previous call) in scripts.

When it happens

Trigger: Calling obb.economy.chart.fred() (or to_chart on a FRED-style dataset) after fetching data with provider='yfinance'/'oecd'/'fmp'; supplying external data= without going through a FRED request.

Common situations: Copy-pasting a charting snippet from another provider's docs, charting a user-provided DataFrame via the FRED chart method, or a provider default resolving to something other than fred.
