Pardot Create Email action fails over 2,880 characters – still a Known Limitation?

I'm running into an issue with the Zapier → Salesforce Account Engagement (Pardot) integration and wanted to see if anyone has found a workaround or if Zapier has addressed this since it was previously reported.

Issue:
When I use the Pardot "Create Email" action and pass a full HTML email body, the Zap fails with:

Error during execution:
Cannot read properties of undefined (reading '@attributes')

After troubleshooting, I found that:

• Small HTML emails work successfully.
• Larger HTML emails fail consistently.
• The failure appears to occur around the ~2,880 character mark.
• The HTML itself is valid and sends correctly when significantly shortened.
• The error appears to be coming from the Zapier connector/parser rather than Pardot returning a useful validation error.

Questions:

1. Is the ~2,880 character limit still a known limitation of the Pardot Zapier integration?
2. Has anyone successfully sent larger HTML emails through this action recently?
3. Is there a documented workaround besides:
   • Creating the email/template directly in Pardot and triggering it via Zapier
   • Using a custom Webhook/API call instead of the native Zapier action
4. Has Zapier acknowledged or fixed the @attributes parsing error?

For context, the HTML contains:

• Tables
• Inline CSS
• Images
• Pardot merge fields
• Tracking parameters in URLs

Nothing unusual for a standard marketing email.

I'd appreciate any updates from Zapier staff or anyone who has implemented a reliable workaround.
