Error message

request failed without response

What it means

Raised by EtoroClient.request when the retry loop ended without any response and without any captured exception — a defensive sentinel for an impossible/degenerate state (e.g. zero iterations or a handler that swallowed the error).

Solutions

1. Check the retry-loop configuration (attempts must be >= 1)
2. Report as a bug in the client if reached with stock configuration
3. Add logging around the retry loop to see which path was taken

try:
    resp = client.request('GET', path)
except EtoroAPIError as exc:
    if 'without response' in str(exc):
        report_bug_to_client_maintainer()
    raise

When it happens

Trigger: Extremely rare: misconfigured retry count of 0, or an exception path that does not record last_exc. In practice, treat as an internal invariant failure rather than an environmental one.

Common situations: Custom subclass or monkeypatched transport that returns without raising or producing a response; edge-case in retry loop logic.
