<![CDATA[FreeMarker error: postMethod variable null in registration verify template]]>I'm encountering a FreeMarker template error when users click a verification link, specifically on the registration verify page. The error indicates that the postMethod variable is evaluating to null:

FreeMarker template error:
The following has evaluated to null or missing:
==> postMethod  [in template "registration/verify.ftl" at line 16, column 30]

The problematic line in my registration/verify.ftl template is:

[#if verificationId?? && postMethod]

This error seems to occur when the verification link is clicked a second time. The stack trace shows:

freemarker.core.InvalidReferenceException
  at freemarker.core.NonBooleanException.<init>
  at freemarker.core.Expression.modelToBoolean
  at freemarker.core.AndExpression.evalToBoolean
  at freemarker.core.IfBlock.accept

Is there a recommended way to handle this variable safely in the template to prevent this error?

To fix this, you need to provide a safe fallback for the postMethod variable. Update line 16 in your registration/verify.ftl template from:

[#if verificationId?? && postMethod]

To:

[#if verificationId?? && (postMethod!false)]

The !false syntax provides a default value of false when postMethod is null or missing, preventing the FreeMarker exception.

Steps to apply the fix:

  1. Navigate to Customizations → Themes in the FusionAuth admin UI
  2. Edit your theme
  3. Locate the registration/verify.ftl template
  4. Update the conditional check as shown above
  5. Save the theme

This pattern can be applied to other templates where variables might be null or missing in certain execution paths.

Why this happens:

According to the FusionAuth documentation, the postMethod variable is not a standard template-specific variable for the /registration/verify template. It is typically available on other verification templates like /email/verify (where it defaults to true). The registration verify template is rendered when a user clicks the URL from the verification email and the verificationId has expired or is invalid. In these scenarios, postMethod may not be set in the template context, which causes the FreeMarker error when attempting to evaluate it as a boolean.
