Error message

Unexpected error: #{response.code} - #{response.body}

What it means

The else-branch of handle_response: any status outside 200/201/400/401/403/404/429/500-599 - e.g. 202/204-style 2xx the case statement forgot, 3xx redirects, or odd 4xx like 405/410/418. Logged with code and body, then raised as Error(:unknown) with both embedded in the message.

Solutions

1. Grep logs for 'IndexaCapital API: Unexpected response - Code:' - the code and body are printed there before the raise
2. Parse the leading number out of e.message to classify: 3xx means wrong URL, 2xx means the case statement needs a new arm, other 4xx means a new error condition
3. Capture response details via DebugLogEntry and report to Indexa support if it persists
4. Extend the when-clauses in handle_response once the new status is understood

Example fix

# before
rescue Provider::IndexaCapital::Error => e
  rollbar.report(e) # all unknowns alert identically

# after
rescue Provider::IndexaCapital::Error => e
  code = e.message[/\AUnexpected error: (\d{3})/, 1].to_i
  if code.between?(300, 399)
    Rails.logger.error("Indexa redirect - BASE_URL drift? #{e.message}")
  else
    rollbar.report(e)
  end
end

def indexa_unknown_status?(error)
  error.is_a?(Provider::IndexaCapital::Error) && error.error_type == :unknown
end

def indexa_unknown_code(error)
  error.message[/\AUnexpected error: (\d{3})/, 1].to_i
end

begin
  provider.list_accounts
rescue Provider::IndexaCapital::Error => e
  raise unless e.error_type == :unknown
  code = e.message[/\AUnexpected error: (\d{3})/, 1].to_i
  Rails.logger.error("Indexa unmapped status #{code}: #{e.message}")
  DebugLogEntry.capture(category: :indexa, level: :error,
    message: e.message, metadata: { status: code })
  raise
end

When it happens

Trigger: Indexa introduces a 202 Accepted for async operations; an http->https or domain redirect (301/302) because of a BASE_URL change; a load balancer returning 507/418-style codes; anything unmapped after an API version bump.

Common situations: Undocumented status codes appearing after provider deploys, redirect chains from API domain migrations, gateway-specific codes between the client and the origin server.
