AD B2C policy error There is a duplicate key sequence

Question

I was following this page to migrate to “Self-service password reset” flow. I added a technical profile as this step

When I upload the policy, I get the following error:

Validation failed: 1 validation error(s) found in policy "B2C_1A_TRUSTFRAMEWORKEXTENSIONS" of tenant xxxx. Schema validation error found at line 1605 col 10 in policy "B2C_1A_TRUSTFRAMEWORKEXTENSIONS" of xxxx.There is a duplicate key sequence 'LocalAccountWritePasswordUsingObjectId' for the 'http://schemas.microsoft.com/online/cpim/schemas/2013/06:UniqueTechnicalProfileId' key or unique identity constraint.Schema validation error found at line 1605 col 10 in policy "B2C_1A_TRUSTFRAMEWORKEXTENSIONS" of tenant xxxx: There is a duplicate key sequence 'LocalAccountWritePasswordUsingObjectId' for the 'http://schemas.microsoft.com/online/cpim/schemas/2013/06:UniqueTechnicalProfileId' key or unique identity constraint.

Not sure if it was related to another already exist ClaimProvider in the same policy or

<ClaimsProvider>
….
      </TechnicalProfile>
        <TechnicalProfile Id="LocalAccountWritePasswordUsingObjectId">
          <Metadata>
            <Item Key="setting.showCancelButton">false</Item>
…

Issue: Uploading B2C_1A_TRUSTFRAMEWORKEXTENSIONS fails with error

There is a duplicate key sequence 'LocalAccountWritePasswordUsingObjectId' for the 'http://schemas.microsoft.com/online/cpim/schemas/2013/06:UniqueTechnicalProfileId' key or unique identity constraint.Schema validation error found at line 1605 col 10 in policy "B2C_1A_TRUSTFRAMEWORKEXTENSIONS" of tenant xxxx: There is a duplicate key sequence 'LocalAccountWritePasswordUsingObjectId' for the 'http://schemas.microsoft.com/online/cpim/schemas/2013/06:UniqueTechnicalProfileId' key or unique identity constraint.

Cause:

B2C_1A_TRUSTFRAMEWORKEXTENSIONS.xml already had a ClaimsProvider with <DisplayName>Local Account SignIn</DisplayName> that handled local account and got the <TechnicalProfile Id="LocalAccountWritePasswordUsingObjectId">

Solution:

1. Adding the <TechnicalProfile Id="ForgotPassword"> and <TechnicalProfile Id="SelfAsserted-LocalAccountSignin-Email">
2. Updated the <TechnicalProfile Id="LocalAccountWritePasswordUsingObjectId">

Thanks,
