Problem using OAuth2 Bearer Token in Azure B2C REST Call - rest

Question

I am calling a REST API with a bearer token from my self-asserted-login technical profile. I have placed the call in the validation profiles as below -
<TechnicalProfile Id="SelfAsserted-LocalAccountSignin-Username">
<DisplayName>Local Account Signin</DisplayName>
<Protocol Name="Proprietary" Handler="Web.TPEngine.Providers.SelfAssertedAttributeProvider, Web.TPEngine, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
<Metadata>
<Item Key="SignUpTarget">SignUpWithLogonUsernameExchange</Item>
<Item Key="setting.operatingMode">Username</Item>
<Item Key="setting.showSignupLink">False</Item>
<Item Key="setting.forgotPasswordLinkLocation">none</Item>
<Item Key="ContentDefinitionReferenceId">api.signuporsignin</Item>
</Metadata>
<IncludeInSso>false</IncludeInSso>
<InputClaims>
<InputClaim ClaimTypeReferenceId="signInName" />
</InputClaims>
<OutputClaims>
<OutputClaim ClaimTypeReferenceId="signInName" Required="true" />
<OutputClaim ClaimTypeReferenceId="password" Required="true" />
<OutputClaim ClaimTypeReferenceId="objectId" />
<OutputClaim ClaimTypeReferenceId="authenticationSource" />
</OutputClaims>
<ValidationTechnicalProfiles>
**<ValidationTechnicalProfile ReferenceId="SecureREST-AccessToken" ContinueOnError="false"/>
<ValidationTechnicalProfile ReferenceId="REST-UserMigration-LocalAccount-SignIn" ContinueOnError="true" />
<ValidationTechnicalProfile ReferenceId="login-NonInteractive"/>**
</ValidationTechnicalProfiles>
<UseTechnicalProfileForSessionManagement ReferenceId="SM-AAD" />
</TechnicalProfile>
I can trace that the REST call is being made successfully with the bearer token in the header. However, the "login-NonInteractive" is not working. It is giving error "invalid username or password". However, if I remove below two steps the "login-NonInteractive" works fine.
It seems like there is a side effect from OAuth2 enabled REST call and "login-NonInteractive". They should be completely unrelated but the strange behavior halting my production.
**<ValidationTechnicalProfile ReferenceId="SecureREST-AccessToken" ContinueOnError="false"/>
<ValidationTechnicalProfile ReferenceId="REST-UserMigration-LocalAccount-SignIn" ContinueOnError="true" />**
Any help would be very much appreciated.
