I have a Lightning Component embedded in a Visualforce page using Lightning Out.

For users with Salesforce Platform license the page doesn't load at all. Instead I get following error in JS console:

https://enxoo-cpq-dev-ed--c.eu6.visual.force.com/c/CPQ_CONF00_OutApp.app?aura.format=JSON&aura.formatAdapter=LIGHTNING_OUT 404 (Not Found)

enter image description here

Changing user license back to Salesforce and everything works fine - page loads normally.

I have my domain enabled in the environment.

Is there any magic trick that should be done to enable that?

  • Do you mind showing your lightning out tag in your vf ? Oct 27, 2016 at 12:33
  • Can you recompile all your classes and make sure users with Salesforce Platform profile have access to the Apex Classes related to your Lightning Component. I've seen LIGHTNING_OUT 404 Error when one of the classes related to the Lightning Component become invalid and required recompilation.

  • I did that. All classes compile successfully and users with these licenses have access to all classes / pages both with Permission Set. Oct 28, 2016 at 8:08

The problem was that one of the aura:attribute had sObject type declared that was only available for Salesforce license users.

<aura:attribute name="contract" type="Contract"/>

To solve it you can change it to

<aura:attribute name="contract" type="Object"/>

But you need to take into account that non-Salesforce license users will not see that object.
