Server error 500 after upgrade of Puppet Enterprise 2023.5 to 2023.7

[xf7803]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 8.6.0-1 (agent) 2023.7 (Puppet Enterprise)
• Ruby: 1:3.0~exp1
• Distribution: Ubuntu 22.04
• Module version: 1.1.0

How to reproduce (e.g Puppet code you use)

Everything was working fine with PE 2023.5, but I not have the error after upgrading to PE 2023.7

What are you seeing

When I run puppet on a node, I get the following error
puppet agent -t
Info: Refreshing CA certificate
Info: CA certificate is unmodified, using existing CA certificate
Info: Refreshing CRL
Info: CRL is unmodified, using existing CRL
Info: Using environment 'production'
Info: Retrieving pluginfacts

Notice: Requesting catalog from xxxxxxxx
Notice: Catalog compiled by xxxxxxxx
Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Function Call, Error executing http request (file: /etc/puppetlabs/code/environments/production/modules/active_directory/manifests/init.pp, line: 16, column: 20) on node xxxxxxxx
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run

The error happens on the following code line:
$join_password = vault_lookup::lookup('xxxxxxxx', {
'vault_addr' => lookup('vault_lookup::vault_addr'),
'auth_method' => lookup('vault_lookup::auth_method'),
'approle_path_segment' => 'v1/auth/approle/',
'role_id' => lookup('vault_lookup::role_id'),
'secret_id' => lookup('vault_lookup::secret_id'),
'field' => $join_username,
}).unwrap

What behaviour did you expect instead

That the lookup works fine and the execution keep going.

Any additional information you'd like to impart

I verified that the server communicates well on the port (no firewall blocking) and that the approle is working correctly.
