Can't reproduce payment instrument token creation action from sandbox

[MitchelBrayon]

I want to create a token for card with given API call https://developer.cybersource.com/api-reference-assets/index.html#token-management_payment-instrumen... /omeglz as CyberSource's Intro video suggests. With default credentials that sandbox provide(testrest merchant) everything goes fine but when I use my credentials generated in https://ebc2test.cybersource.com /echat I am always omegle.2yu.co getting next error(I don't edit initial request that sandbox provides; with this exact request and default credentials CyberSource generates token and successfully returns it to API test page)

{
    "errors": [
        {
            "type": "forbidden",
            "message": "Invalid profile owner"
        }
    ]
}

I have tried to use merchant API shared key/secret as well as user-specific credentials from the same merchant profile.

What I did wrong(may be I need to change smth in merchant profile) and what I need to do to make it work ?

Could you share the merchantId you are using so I can take a look ?

Additionally, try sending the request without the profile-id header and share the findings. If that does not solve, we need to look into merchant account settings. This seems a merchant account set up issue.
