Failed to map URL. Error: {response}

Error message

Failed to map URL. Error: {response}

What it means

Raised by async map_url in the fall-through else branch — the response had neither success+links nor an 'error' field. The entire response dict is interpolated, often producing an opaque repr. Indicates an unexpected response shape rather than a documented failure.

Solutions

1. Upgrade the python-sdk to match your Firecrawl server version.
2. Log the full response object to identify the unexpected shape.
3. If self-hosted, align server and SDK releases.

Example fix

// before
links = await app.map_url(url)
// after
# align versions and log raw response
raw = await app._async_post_request(f'{app.api_url}/v1/map', params, {'Authorization': f'Bearer {app.api_key}'})
logger.debug('map raw: %s', raw)

null

null

try:
    links = await app.map_url(url)
except Exception as e:
    log.error('unexpected map response: %s', e)
    # align SDK/server versions, then retry
    raise

When it happens

Trigger: Server returned an undocumented JSON variant, a maintenance payload, or a version-mismatch response the SDK does not model. The lack of 'error' key means the SDK has no specific message to surface.

Common situations: SDK version out of sync with server, a proxy rewriting responses, or a server bug producing a non-standard body.
