Grails NPE in java.net.URI$Parser.parse() when sending mail inside Quartz

Question

We have a scheduled invoicing service, where we send invoices to customers' email.

asynchronousMailService.sendMail {
            multipart true
            to emailTo.split("[,;]")
            bcc bccString
            from fromString
            subject subjectString
            html view:'/email/invoiceEmailTemplate',
                    model: [companyName: companyName, customerFirstName:  order.customer.firstName,
                            xeroInvoiceId: invoice.invoiceNumber, invoiceTotal: order.totalAmount,
                            invoiceUrl: invoiceUrl,
                            currencyCode: invoice.currencyCode, dueDate: invoice.dueDate]
            attachBytes invoice.invoiceNumber+".pdf" , 'application/pdf', invoiceBytes
        }

Causing this error:

The above error logs only happen in production server and I have no success in replicating on my local machine and dev server.

Any ideas?

@renz paste code of com.mycompany.thirdparty.InvoiceService.groovy, especially method:emailInvoiceToCustomer() and bold line:118 — Michal_Szulc, Mar 09 '16 at 08:36
@YassinHajaj Do you even understand the question? Have you ever used Grails? — renz, Mar 09 '16 at 11:13
@MichalSzulc The above code is what those lines are referring to — renz, Mar 09 '16 at 11:14

I answered that question once here: Grails Mail service not working with guartz scheduler in war mode

It's the AsyncMail unable to get the server's URL. The simplest thing is to configure it via the grails.serverURL config property.

How would that work for multi-tenancy? We have different serverUrl per tenant. – renz Mar 09 '16 at 11:15
Can I provide a custom LinkGenerator? – renz Mar 09 '16 at 11:19
