## Describe the problem/error/question
When using the WhatsApp Business Cloud n…ode with dynamic values for the recipient phone number or text body, the workflow execution fails with the error "No execution data available."
The issue only occurs when using parameters in the recipient or text fields. If both values are hardcoded, the message sends successfully.
Things I’ve Tried (Still Getting the Error):
✅ Converted values to .toString() → Still fails.
✅ Added a "Set" node before the WhatsApp node → Same issue.
✅ Tried different combinations of fixed/dynamic values:
Fixed phone + dynamic text → ❌ Error
Dynamic phone + fixed text → ❌ Error
Fixed phone + fixed text → ✅ Works
✅ Copied and pasted the entire workflow into a new one → Same error.
The only way to get the message to send is if both the phone number and text body are hardcoded.
## What is the error message (if any)?

Observed Behavior: 1. Phone Number Formatting Issue: • In previous versions, phone numbers like +31688888188 and +31619971032 were correctly recognized. • After the update, the workflow fails to detect or replace phone numbers correctly in formatted messages. • Possible Cause: The update may have changed how Regex or text processing works inside n8n. 2. Message Delivery Problems: • WhatsApp messages generated inside n8n are not being processed as expected. • Some messages fail to format correctly (e.g., links or rich text not displaying properly). • The WhatsApp node may not be encoding messages correctly before sending. 
Impact: • Workflows using WhatsApp messaging no longer function correctly. • Businesses relying on WhatsApp for automated responses or confirmations may experience failures. • Users have to manually correct messages before sending. 
Possible Causes: • Changes in n8n’s text processing engine. • Updates to the WhatsApp API handling within n8n. • Issues with new dependency versions (e.g., WhatsApp libraries). 
Suggested Fixes: • Rollback n8n to an earlier working version as a temporary fix. • Check changelogs for updates that might have modified text processing. • Verify WhatsApp API changes that could affect message formatting. • Re-test regex conditions in workflows to ensure proper detection. 
Steps to Reproduce the Issue: 1. Upgrade to the latest n8n version. 2. Run a workflow that formats a WhatsApp message (e.g., inserting phone numbers). 3. Observe that phone numbers are not replaced correctly or messages fail to send properly.
