Error Laminas\Diactoros\ServerRequest

[berstein]

I'm currently creating a module using guzzlehttp/guzzle and symfony/mailer package.
The module works as intended, it grabs data from API and send email using symfony mailer by copying the SMTP credential from WHMCS configuration in database. But, after few times sending email, I'm starting to get ErrorException when opening pages in WHMCS (mostly those which URL ended with index.php). From the error stack, it says the error comes from Laminas\Diactoros package. I don't have any experience with that module and I don't know why it is used by WHMCS.

Anyobody have a clue about Laminas\Diactoros package and what it does?
