“Supermetrics is a Bitter Experience! We can pull data from nearly any tool, schedule updates, manipulate data in Sheets, and push data back into our systems.”
The “Cannot read property length from undefined” error happens when your Salesforce connector tries to process data that doesn’t exist, usually because of failed API calls or authentication issues.
This JavaScript error means your connector got field information but couldn’t fetch the actual records. Here’s how to solve it permanently.
Eliminate undefined length errors using Coefficient
Unlike generic third-party connectors that lack robust error handling, Coefficient prevents these errors entirely through advanced authentication management and intelligent API handling. The platform automatically validates permissions and handles authentication states properly.
How to make it work
Step 1. Connect Salesforce through Coefficient’s native integration.
Open Google Sheets and install Coefficient from the workspace marketplace. Click “Connect to Salesforce” and authenticate with your credentials. Coefficient supports MFA and automatically handles token refresh to prevent authentication failures.
Step 2. Select your data source with built-in validation.
Choose from existing Salesforce reports, objects and fields, or custom SOQL queries. Coefficient validates field-level permissions before import, preventing the scenarios where metadata loads but data doesn’t.
Step 3. Import with automatic error handling.
Click “Import” and Coefficient handles API limits, permission validation, and retry logic automatically. The system provides clear error messages instead of cryptic undefined length errors if any issues occur.
Step 4. Set up reliable refresh schedules.
Configure automatic refreshes (hourly, daily, or weekly) with built-in error recovery. Coefficient’s smart retry logic works within Salesforce API limits and prevents timeout issues that cause undefined responses.
Keep your data flowing smoothly
Coefficient’s native Salesforce integration eliminates the technical complexities that cause undefined length errors in other connectors. Get started with reliable Salesforce data imports today.
