Activate Session-Based Permission Sets Without Code

I am not able to complete the challenge. Getting the error code as : KQECBABH

I am unable to successfully login using the Salesforce DX CLI. I have tried numerous techniques, all to no avail. In am on Windows 10 utilizing the latest version of the CLI from Powershell and Google Chrome as my web browser.

As a side note, the "sfdx update" command works successfully.

Technique 1. When logging in using what is supposed to be the easiest approach by using force:auth:web:login, the CLI opens a web browser. Once I enter my credentials, the OAuth flow calls back into localhost:1717, but apparently the CLI isn't listening. Chrome complains with an ERR_EMPTY_RESPONSE and no response payload. Command line indicates "Unable to verify the first certificate." Turning on logging (even at the trace level) does not reveal any additional information.

Technique 2. I created a self-signed certificate using openssl along with a new connected app. Then using the CLI, I utilized the force:auth:jwt:grant function. This failed with the same error message as above: "Unable to verify the first certificate."

Technique 3. I disabled SSL verification and strict SSL in npm and forced the CLI to go through Fiddler. I then configured Fiddler to ignore certificate errors. Still, neither one of the above techniques worked after this.

Any idea what I'm doing wrong?

Has anyone completed this trail? I am stomped on challenge number 3, regarding created the process for fulfillment. Any pointers or guidance would be appreciated.
 

Hi, I am having trouble with the "Attributes and Expressions" module from trailhead.

Here is the challenge:
Create a Lightning Component to display a single item for your packing list.

• Create a component called campingListItem that displays the name (ui:outputText) and the three custom fields using the appropriate output components.
• Add an attribute named 'item' for type Camping_Item__c.

I created an component named campingListItem and this is the code:

<aura:component >
    <aura:attribute name="item" type="<my_domain>__Camping_Item__c"/>
    
    <ui:outputText value="{!v.item.Name}"/>
    <ui:outputCheckbox value="{!v.item.<my_domain>__Packed__c}"/>
    <ui:outputCurrency  value="{!v.item.<my_domain>__Price__c}"/>
    <ui:outputNumber value="{!v.item.<my_domain>__Quantity__c}"/>
</aura:component>

The error that I am getting is: "Challenge Not yet complete... here's what's wrong: 
The packingListItem Lightning Component's attribute tag doesn't exist or its attributes are not set correctly."

With this, I tried to create another component, with the name "packingListItem", but It didn't work.

Can anyone help me?

Thanks,

View state is not maintained for transient instance variables  and static variables also. Then what exactly is the difference between transient instance variable and  static variable ?
