                attributes: {
                    objectApiName: 'Corrective_Action__c',
                    defaultFieldValues: {
                        "Key_Action__c" : this.principlerecid
                    },
                    recordTypeId : this.correctiveActionId,
                    actionName: 'new'
                }
            },true);

Answer 1

This is a kind of limitation in Lightning web Component. Setting default values isn't yet supported, and planned for an upcoming release.

I have created one idea on this:- Allow setting pre-default values in record form by navigation service in LWC

You can upvote this. For time being continue using force:createrecord in your aura Component.

Update

In spring 20, this feature has been delivered by Salesforce.

See this link. According to it, We can do this as follow:-

this[NavigationMixin.Navigate]({
            type: 'standard__objectPage',
            attributes: {
                objectApiName: 'Account',
                actionName: 'new'                
            },
            state : {
                nooverride: '1',
                defaultFieldValues:"Name=Salesforce,AccountNumber=A1,AnnualRevenue=37000,Phone=7055617159"
            }
});

The ability to navigate to a new record with default values has been added to LEX, and ready for use in both Aura and LWC components as of Spring 20, as specified in the release notes.

There is a good example that can be found in Aura documentation right now, but the LWC documentation is still missing at this point, because although referenced in the docs, the link (https://developer.salesforce.com/docs/component-library/bundle/lightning-pageReferenceUtils/documentation) is currently broken. Hopefully this will be addressed soon.

For now, there is a recipe in the lwc-recipes sample app. Here is the JS code. Note use of lightning/pageReferenceUtils to encode the default values:

import { LightningElement } from 'lwc';
import { NavigationMixin } from 'lightning/navigation';
import { encodeDefaultFieldValues } from 'lightning/pageReferenceUtils';

export default class NavToNewRecord extends NavigationMixin(LightningElement) {
    // below, we take an object and encode it to work with navigation
    navigateToNewContactWithDefaults() {
        const defaultValues = encodeDefaultFieldValues({
            FirstName: 'Morag',
            LastName: 'de Fault',
            LeadSource: 'Other'
        });

        this[NavigationMixin.Navigate]({
            type: 'standard__objectPage',
            attributes: {
                objectApiName: 'Contact',
                actionName: 'new'
            },
            state: {
                defaultFieldValues: defaultValues // and here we set defaults as a nav parameter
            }
        });
    }
}

One note, sfdx-lwc-jest currently has not implemented the required package lightning/pageReferenceUtils, so you will not be able to test without mocking this package. An issue has been raised in that repo. For now, the recipes app has left a commented-out-but-most-likely-working test in place.

To construct a custom button or link that launches a new record with prepopulated field values, use this sample formula:

/lightning/o/Account/new?defaultFieldValues=
    Name={!URLENCODE(Account.Name)},
    OwnerId={!Account.OwnerId},
    AccountNumber={!Account.AccountNumber},
    NumberOfEmployees=35000,
    CustomCheckbox__c={!IF(Account.SomeCheckbox__c, true, false)}

This is now supported in spring 20. Here is a code sample for you.

this[NavigationMixin.Navigate]({
            type: 'standard__objectPage',
            attributes: {
                objectApiName: 'Account',
                actionName: 'new'                
            },
            state : {
                nooverride: '1',
                defaultFieldValues:"Name=Tushar Sharma,AccountNumber=55555,NumberOfEmployees=35000,Phone=9988776655,Site=https://newstechnologystuff.com/"
            }
        });

We can use state parameter with defaultFieldValues to provide default values.
