I want to embed external content in my dashboard (cloudfront distibution link) that is hosting an angular app that asks you to authentify then displayes for you a dashboard. When i want to authentify i get this error

“[d2cymu1pvrh8xe.cloudfront.net/:1](http://d2cymu1pvrh8xe.cloudfront.net/:1) Blocked form submission to ‘’ because the form’s frame is sandboxed and the ‘allow-forms’ permission is not set.”  
When i go to inspect the page i find that the iframe that hubspot created for us to put the external content in has the sandbox attribute with no allow-forms permission

Hubspot iframe

i also tried to useing the Design Tools and create my own Module but i get the same error as the top iframe has the same attribute.  
This is my second time posting about this issue i would appreciate the help if someone had the same issue. My goal is to embed my app in hubspot and be working it doesn’t have to be in a Dashboard

Hey @YoussefCL thank you for posting in our Community!

This error typically occurs when the form is embedded in an iframe and the iframe is sandboxed without the ‘allow-forms’ permission. To resolve this issue, you can follow these steps:  
- Edit the page where the form is embedded.  
- Locate the iframe code that contains the form.  
- Add the ‘allow-forms’ permission to the iframe code.  
- Save the changes and publish the page again.  
- Test the form submission to see if the issue is resolved.

If you are not able to resolve the issue, I want to share this[knowledge base here with more information](https://knowledge.hubspot.com/forms/troubleshoot-hubspot-forms)

Kindly,

Pam

I don’t believe you have read my question proprely, I’am trying to embed external content in a dashboard, the external content has a form that when i go ahead and submit it, i get an error blocked from submission because the iframe that we add the external content to (created and controled by Hubspot) is sandboxed and doesn’t have the allow-forms permission set. I included a screenshot from the dashboard page’s code that proves what i’m saying. I will add one more screen shot of my external content

Anyone have any ideas on what work around on this? Currently have the same setup. I need some authentication (form submission) to see the generated reports from my domain/url?  
Thank you!

Same problem here 2 years later.  
Blocked form submission to ‘’ because the form’s frame is sandboxed and the ‘allow-forms’ permission is not set.Understand this errorAI. This is when I try to add a new contact to the CRM.
