Url Personalization is not working with contextual attributes in AJO

Hi All,

We are trying to render a dynamic URL in an email button based on the contextual event attribute:
context.journey.events.`1116xyz`._tenant.applications.applicationType. The attribute applicationType is a string datatype and contains values such as:
"1"/"2"
Based on this value, we want to display different URLs in the email CTA button.

The logic implemented is( replaced with dummy values ):
{% let AppType = context.journey.events.`1116xyz`._tenant.applications.applicationType %}
{%#if AppType = "1"%}   
<a href="https://www.google.com/">Accept my Offer</a>
{%else if AppType = "2"%}  
  <a href="https://onboarding.xyz.com/">Accept my offer</a>
{%/if%}

If we click on validate. Validation successful.When we attempt to save the email content template in the journey, the validation fails with the PQL parsing error and the journey cannot be saved.

 Invalid syntax Invalid syntax Error in parsing PQL expression "context.journey.events.`1116xyz`._tenant.applications.applicationType="1&quot;": line 1:71 token recognition error at: '&'
Invalid syntax Invalid syntax Error in parsing PQL expression "context.journey.events.`1116xyz`._tenant.applications.applicationType=&quot;In 2&quot;": line 1:71 token recognition error at: '&'

Thanks
