what changes should  i make to the code please help

I have an Issue with this component. When every Try to submit a new OpportunityLineItem
The component sends the following error messages. 
 

An error occurred while trying to update the record. Please try again.
    ProdConfigCreateOppItem.js:59 undefined
    ProdConfigCreateOppItem.js:60 REQUIRED_FIELD_MISSING
    ProdConfigCreateOppItem.js:61 Required fields are missing: [OpportunityId]

The problem is that I'm actually sending the required fields, also, I've tried Intercepting the request, and adding the fields manually in an `onsubmit` function.
I read the component documentation and no hint about this. 

Any Idea what It's wrong?  

<lightning:recordEditForm
            onload="{!c.handleLoad}"
            onsuccess="{!c.handleSuccess}"
            onerror="{!c.getError}"
            objectApiName="OpportunityLineItem"
