This charting method does not support

Error message

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

What it means

The maritime chokepoint info chart (economy_shipping_chokepoint_info) is provider-specific: it delegates rendering to openbb_imf.views.maritime_chokepoint_info, which only understands IMF-SDB response shapes. If the provider attached to the data is not 'imf', it raises RuntimeError immediately instead of attempting to plot foreign data.

Solutions

Request the data with provider='imf': obb.economy.shipping.chokepoint_info(provider='imf').
For other providers, extract the results (res.to_df()) and build the figure with the generic charting API.

Example fix

# before
res = obb.economy.shipping.chokepoint_info(provider='custom').charting.to_chart()

# after
res = obb.economy.shipping.chokepoint_info(provider='imf')
fig, content = res.charting.to_chart()

Defensive patterns

Strategy: validation

Validate before calling

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

Try / catch

try:
    fig, content = views.economy_shipping_chokepoint_info(**kwargs)
except RuntimeError as e:
    if 'does not support' in str(e) and 'imf' in str(e):
        kwargs['provider'] = 'imf'  # refetch with imf, then retry
    else:
        raise

Prevention

Pin provider='imf' on shipping data requests feeding the chart.
Use generic charting for non-IMF shipping data.

When it happens

Trigger: Calling obb.economy.shipping.chokepoint_info(...).charting.to_chart() (or the view directly) with a non-IMF provider, or with provider unset/None while injecting external data.

Common situations: Fetching chokepoint data from an alternative provider then applying the default charting route, or writing a custom integration that bypasses the IMF fetcher.
