Problem to test SAML login sequence from HTML page


I am testing SAML login sequence , trying to implement auth0 article
“Test SAML SSO with Auth0 as Service Provider and Identity Provider”

I’ve succeeded to pass the step
“Test connection between service and identity provider”

but when I am trying to run HTML file I get Auth0 popup "Something went wrong , please contact technical support "

Actually in debugger I see that I got erroreven before pressing on Login button

Failed to load resource: the server responded with a status of 404 ()
index.js:493 Uncaught Error: Error: An error occurred when fetching client data for Lock: could not be loaded.
at index.js:493:7

Please help


Hi @eliahut

Thanks for getting in touch with us at Auth0 Community.

Please can you ensure you’re running the latest version of Lock i.e.

<!-- Latest patch release (recommended for production) -->
<script src=""></script>

This should resolve the issue.

Warm regards.
