Sitecore 10.2 uses Sitecore Headless Rendering 19.0.0. See link here

See this blog for prerequisites and setting jss using next js in disconnected mode.

Follow below steps after the steps completed in above blog

Download Sitecore Headless Services for Sitecore XM

Prerequisite

Install Sitecore 10.2 XP0 on local development environment. See hte blog here if not already installed

Install downloaded package for Headless Service

Run the next js app in connected mode

Before working on connected mode create API Key

Navigate to – /sitecore/system/Settings/Services/API Keys

Create a new API Key e.g.:- nextjsservice

API key here is Item ID

Create a custom binding-

For this create a self signed certificate with a custom domain name in this case – next-jss-prj.dev.local

New-SelfSignedCertificate -CertStoreLocation C:\certificates -DnsName "next-jss-prj.dev.local" -FriendlyName "My First Next JSS App" -NotAfter (Get-Date).AddYears(10)

Create a new https binding and assign the newly create SSL certificate

Setup JSS

Run the command

jss setup

Provide the path to the Sitecore instance – e.g.:- C:\inetpub\wwwroot\XP0.sc

Provde the host name – e.g.:- https://next-jss-prj.dev.local

Import Service url – e.g.:- https://next-jss-prj.dev.local/sitecore/api/jss/import

Provide the Sitecore API Key – i.e. the Item ID of the key created earlier in my case it is -{8FCF8D4A-8421-4406-B658-800C48796F8E}. See screenshot

Deployment secret– Leave this blank as this will generate new secret key

Deployment secret key is generate and stored in <<jss development folder>>\sitecore\config\next-jss-prj.deploysecret.config

JSS connection settings saved to scjssconfig.json

Connection and the deployment secret is created, now this needs to be deployed to Sitecore instance so the JSS app is able to establish a connection with Sitecoore

To deploy the config setting deploy the config to Sitecore instance-

jss deploy config

Configs are copied to Sitecore instance App_Config\Include\zzz…

Deploy the artifacts to Sitecore instance-

Since we don’t know hte thumbprint use the below command with –acceptCertificate as test

jss deploy app –includeContent –includeDictionary –acceptCertificate test

This will provide the thumbprint. highllighted in red

Copy the certificate and try deploying again-

jss deploy app –includeContent –includeDictionary –acceptCertificate E4:54:12:A0:7E:D5:95:9B:B0:C2:00:17:3A:26:1B:AD:71:73:9F:05

To run the app run following command

jss start:connected

If you receive this error-

Execute following command to get this working on port 3000

$env:NODE_TLS_REJECT_UNAUTHORIZED=0

Execute JSS start again-

jss start:connected

ERROR-

Connection to your rendering host failed with a Not Found error. Ensure the POST endpoint at URL http://localhost:3000/api/editing/render has been enabled.

Copy the deploy secret and update the – value of setting of JavaScriptServices.ViewEngine.Http.JssEditingSecret in Sitecore.JavaScriptServices.ViewEngine.Http with the deploy secret.

This now work in connected mode. Any content changes in Sitecore should reflect localhost:3000 and Sitecore instance (https://next-jss-prj.dev.local/)

Sitecore next js working in connected mode with SSL

Resolution-

Check if the API key is correct at the location – /sitecore/system/Settings/Services/API Keys

Also check if the CORS and Allowed Controllers are set correctly
