Hi Thiago,

Sorry for this issue you are encountering.

I faced a similar issue in the past and was able to solve it with below approach.

Here is the sample

ComponentCanvas : 
<aura:component implements="force:appHostable,flexipage:availableForAllPageTypes" access="global" >
    <force:canvasApp developerName="canvasappname" namespacePrefix=""  parameters='{"xxx":"123","yyy":"4444"}'    width="infinite" /> 
</aura:component>
component applications: 
<aura:application >
    <c:ComponentCanvas />
</aura:application>
For more information please refer to below link. Please let us know if this helps.

Kindly mark this as solved if the reply was helpful.

Thanks,
Nagendra
