Customer Sync from SFCC to SFSC failing | No auth token available

[ashumahajan-ceo]

During one of the step of installation, a order on behalf anonymous user is created as oobo-ohuvi@crmsync.salesforce.com

However that is not synced with SFSC. I see the following error in field Salesforce Platform Response Text on Customer record:

Mon, 28 Mar 2022 05:33:48 GMT: Status 0 (Error: No auth token available, please verify your configuration! (int_b2ccrmsync/cartridge/scripts/b2ccrmsync/models/authToken.js#82)): ScriptingException:Error: No auth token available, please verify your configuration! (int_b2ccrmsync/cartridge/scripts/b2ccrmsync/models/authToken.js#82)

What could be wrong? Which auth needs to be checked and where?

I am getting the same error if I am creating the user from Stprefront.
