Abridge Common Errors

Overview

Comprehensive troubleshooting guide for Abridge clinical documentation integration. Covers authentication failures, EHR connectivity, audio streaming, note generation, and FHIR push errors.

Error Reference

Authentication & Authorization Errors

Code	Error	Root Cause	Fix
401	INVALID_CREDENTIALS	Expired or wrong partner secret	Rotate credentials in Abridge Partner Portal
401	TOKEN_EXPIRED	SMART on FHIR token expired	Refresh token before 60-min expiry
403	ORG_NOT_PROVISIONED	org_id not activated	Contact Abridge sales engineer
403	SPECIALTY_NOT_LICENSED	Specialty not in contract	Check licensed specialties in Partner Portal
403	PROVIDER_NOT_ENROLLED	Provider not onboarded	Complete provider enrollment in Abridge admin

Session & Encounter Errors

Code	Error	Root Cause	Fix
409	SESSION_ALREADY_ACTIVE	Duplicate session for same encounter	Reuse existing session_id
422	INVALID_SPECIALTY	Unsupported specialty code	Use codes from /specialties endpoint
422	PATIENT_NOT_FOUND	Patient ID not in EHR context	Verify FHIR Patient resource exists
408	SESSION_TIMEOUT	Session idle > 30 minutes	Create new session; old ones auto-expire
500	SESSION_CORRUPTED	Server-side state error	Create new session; report to Abridge support

Audio & Transcription Errors

// Common audio streaming diagnostics
async function diagnoseAudioIssues(wsUrl: string): Promise<string[]> {
  const issues: string[] = [];

  // Check WebSocket connectivity
  try {
    const ws = new WebSocket(wsUrl);
    await new Promise((resolve, reject) => {
      ws.onopen = resolve;
      ws.onerror = reject;
      setTimeout(() => reject(new Error('Connection timeout')), 5000);
    });
    ws.close();
  } catch {
    issues.push('WebSocket connection failed — check firewall allows wss:// on port 443');
  }

  // Check audio format requirements
  // Abridge requires: 16kHz, mono, 16-bit PCM little-endian
  const requiredFormat = { sampleRate: 16000, channels: 1, encoding: 'pcm_s16le' };
  issues.push(`Verify audio format: ${JSON.stringify(requiredFormat)}`);

  return issues;
}

Symptom	Root Cause	Fix
Empty transcript	Microphone not capturing	Check audio input device; verify 16kHz sample rate
Garbled transcript	Wrong encoding	Must be 16-bit PCM LE mono at 16kHz
Speaker mislabeled	Single-channel audio	Use stereo mic or speaker diarization hints
WebSocket drops	Network instability	Implement reconnect with buffered chunks
High latency	Large audio chunks	Send 100ms chunks, not full sentences

Note Generation Errors

// Note generation failure handler
async function handleNoteFailure(sessionId: string, error: any): Promise<void> {
  const status = error.response?.status;
  const code = error.response?.data?.error_code;

  switch (code) {
    case 'INSUFFICIENT_CONTENT':
      console.error('Transcript too short — need at least 30 seconds of clinical conversation');
      break;
    case 'UNSUPPORTED_LANGUAGE':
      console.error('Language not in Abridge supported set (28+ languages)');
      break;
    case 'TEMPLATE_NOT_FOUND':
      console.error('Note template not available — use: soap, hp, progress, procedure');
      break;
    case 'GENERATION_TIMEOUT':
      console.error('Note generation exceeded 120s — complex encounter, retry once');
      break;
    default:
      console.error(`Unknown note error: ${status} ${code}`);
  }
}

FHIR Integration Errors

Error	Root Cause	Fix
FHIR 422 Unprocessable	Invalid DocumentReference	Validate against FHIR R4 schema
FHIR 401 Unauthorized	Epic token expired	Re-authenticate via SMART on FHIR
FHIR 404 Not Found	Wrong FHIR base URL	Verify Epic FHIR endpoint in EHR config
FHIR 409 Conflict	Duplicate document ID	Generate unique DocumentReference IDs
Epic SmartPhrase error	Template mismatch	Verify SmartPhrase names match Epic config

HIPAA Compliance Errors

// PHI leak detection in error logs
function auditErrorLog(error: any): void {
  const serialized = JSON.stringify(error);

  // Check for accidental PHI in error output
  const phiPatterns = [
    /\b\d{3}-\d{2}-\d{4}\b/,        // SSN
    /\b\d{10}\b/,                     // MRN (10-digit)
    /\b[A-Z][a-z]+\s[A-Z][a-z]+\b/,  // Patient names (heuristic)
    /\b\d{1,2}\/\d{1,2}\/\d{4}\b/,   // DOB
  ];

  for (const pattern of phiPatterns) {
    if (pattern.test(serialized)) {
      console.error('WARNING: Possible PHI detected in error log — redact before logging');
      return;
    }
  }
}

Diagnostic Script

#!/bin/bash
# abridge-diagnostic.sh — Run before opening a support ticket

echo "=== Abridge Integration Diagnostics ==="

# 1. Check credentials
echo "Checking credentials..."
curl -s -o /dev/null -w "%{http_code}" \
  -H "Authorization: Bearer $ABRIDGE_CLIENT_SECRET" \
  -H "X-Org-Id: $ABRIDGE_ORG_ID" \
  "${ABRIDGE_BASE_URL}/health"

# 2. Check FHIR server
echo "Checking FHIR connectivity..."
curl -s -o /dev/null -w "%{http_code}" \
  "${EPIC_FHIR_BASE_URL}/metadata"

# 3. Check WebSocket
echo "Checking WebSocket..."
curl -s -o /dev/null -w "%{http_code}" \
  --header "Upgrade: websocket" \
  "${ABRIDGE_BASE_URL/http/ws}/ws/health"
