raise ExtensionError(
sphinx.errors.ExtensionError: Handler <function load_mappings at 0x11e9867a0> for event 'builder-inited' threw an exception (exception: unknown or unsupported inventory version: ValueError('invalid inventory header: <!DOCTYPE html><html><head>'))The Plotly domain mapping is defined in conf.py in the following way:
