error is always displayed on Azure AD B2C, why?

I am trying to display a custom error, idea is user may have several MFA setup, user introduces login, then goes to a screen where he needs to select the MFA that he wants to use, if the MFA is in a list, then he can proceed, if it is not, then we need to display an error. This is my code:

                                   ContentDefinitionReferenceId="api.selfasserted">

                        <ClaimsExchange Id="MFAConfigChecks"

                    </ClaimsExchanges>
                </OrchestrationStep>

I have tested so far for AreConditionsMet and at this stage, when this is true the error is still being display, what am I doing wrong? I think it is taking the default value in any case, but I don't get why it does not workout the value in the SelfAsserted-GettingSelectedMFAParameter technical profile.

<ClaimsTransformation Id="MFAConditionsMet"
                              TransformationMethod="AssertBooleanClaimIsEqualToValue">
            <InputClaims>
                <InputClaim ClaimTypeReferenceId="AreConditionsMet"
                            TransformationClaimType="inputClaim" />
            </InputClaims>
            <InputParameters>
                <InputParameter Id="valueToCompareTo"
                                DataType="boolean"
                                Value="true" />
            </InputParameters>
        </ClaimsTransformation>
