Pulling my hair out on trying to attach an email message to an invoice record. I thought we could just send the email and use the "relatedRecords" option to attach it to a transaction record? Anybody see anything wrong with this simple email send? It won't attach to my invoice record.. thanks for helping

Read the help : "email.send(options)"

I did that of course. Email is sending fine, just not attaching to the record..

Code looks fine. I'm assuming the email is being received, and it's just not visible under communication -> messages on the invoice record. the invoiceId variable in your example is the invoice internal id correct?

Check what type of info the "relatedRecords" param is

@JohnnyC Yes, that's correct. InvoiceId is the internal id and it's not showing up under messages. I tried attaching it to just entity (contact) record but neither seems to work

//Add additional code 
.
var senderId = -5;
var recipientEmail = <mailto:'notify@myCompany.com|'notify@myCompany.com>';
var timeStamp = new Date().getUTCMilliseconds();
var recipientId = 12;
var fileObj = file.load({
    id: 88
});
email.send({
    author: senderId,
    recipients: recipientId,
    subject: 'Test Sample Email Module',
    body: 'email body',
    attachments: [fileObj],
    relatedRecords: {
           entityId: recipientId,
            customRecord:{
                  id:recordId,
                  recordType: recordTypeId //an integer value
                  }
      }
});
...

This is the sample from help.

@Nairolf Ok, but that uses an entity Id and custom record. How do I attach it to a invoice / transaction record? I am creating the invoice in the first step and retrieve the Id. For testing purposes however I am just hard coding it. It's the invoice id shown in the url

@Dan P have you tried declaring your variable as a string.

@JohnnyC Yes I have tried that as well

hum... you're log as admin right?

@Nairolf Admin, correct

don't put the comma after "invoiceId }"

@Nairolf no difference...

I guessed so, it was more to make sure... As @JohnnyC said, everything looks good. Did you try to execute it in the debugger to see what is going on?

@Nairolf Yep, executing through debugger. No errors.. email is sent with attachment but nothing in communication -> messages on the invoice record. Very frustrating. I am in sandbox but that should work there too, I presume.

Hooooo sandbox... I see... Are you able to try it in a production env.?

I can try but it would defeat the purpose of testing all code in Sandbox and having to explain to client it only works in production..

I agree... but sandbox, as you know, there are not very stable 😞

@Nairolf @JohnnyC Ok, seriously. This is the dumbest thing. Exact same code works like a charm in Production. How is that even possible that it won't work in Sandbox? They recently did a refresh so all settings are the same.. How frustrating...

Weird... I had to give it a try and I have no issue on my sandbox account. My sandbox is about a month old since last refresh. I'll have to watch for this on next refresh.

We have so many issues with our sandboxes... Thanks for the feedback @Dan P. Good luck for your project!

@Nairolf Thank you. I appreciate your feedback. @JohnnyC Very strange indeed. Thanks for testing it and letting me know. I am a bit baffled myself.
