From the RelyingParty document I tried to follow everything with an additional set of elements that customize our login session time.
Here is my sample policy code I added:
```
```
Unfortunately this is throwing me the below exception:
Validation failed: 1 validation error(s) found in policy "B2C_1A_SIGNUP_SIGNIN_SAML" of tenant "stgb2crexaad.onmicrosoft.com".Schema validation error found at line 10 col 8 in policy "B2C_1A_SIGNUP_SIGNIN_SAML" of tenant "stgb2crexaad.onmicrosoft.com": The element 'UserJourneyBehaviors' in namespace 'http://schemas.microsoft.com/online/cpim/schemas/2013/06' has invalid child element 'SingleSignOn' in namespace 'http://schemas.microsoft.com/online/cpim/schemas/2013/06'.

Do you say I'm missing anything here?
It seems I'm not authorized to reopen the issue, kindly do so and we can discuss more
@SaurabhSharma-MSFT, Any update on this?
@SaurabhSharma-MSFT, this doesn't seem working to me

@nkumars order of elements matter. In my case, I got same error as you, when I had it like:
<ScriptExecution>Allow</ScriptExecution>
<SessionExpiryType>Rolling</SessionExpiryType>
<SessionExpiryInSeconds>900</SessionExpiryInSeconds>
but when I moved ScriptExecution element down in the list, it started to work (see below)
<SessionExpiryType>Rolling</SessionExpiryType>
<SessionExpiryInSeconds>900</SessionExpiryInSeconds>
<ScriptExecution>Allow</ScriptExecution>
Try to put JourneyInsights after other elements
I have the same problem :

I was able to resolve by moving ScriptExecution below ContentDefinitionParameters, based on what others have said it looks like its expecting this order to be preserved:
