Sendgrid AddUniqueArg problem about sendgrid-go HOT 5 CLOSED

Hi there,

Can you confirm that the UniqueArgs are never being set, or sometimes being set? Can you please also confirm how long you've been using this code, and if this problem has ever been an issue before now?

Thanks!

from sendgrid-go.

rbin, thanks for your quick response!

It is sometimes setting the unique args, maybe a 3rd of the time. I have verified that we are definitely always running the AddUnqiueArg() call with proper non-empty string values..

We have migrated our messaging backend from a solution based on https://github.com/sendgrid/sendgrid-nodejs, where UniqueArgs were working.

So, this code has been in use for the second day today.

Standing by.

Are you using the lastest version of smtpapi-go?

Are this normal strings? or are you using special characters?

Try logging all the strings you are setting to avoid any false positives.

Yes, smtpapi-go is latest commit (commit f898c6a004fb8d48ef1ef3d0e64917c0522ead1c).

We put in logging code yesterday that showed these results:
The values are uuids, for example, "0948c776-9920-4bb8-940b-64de0a58dec9", from my logs:

message.AddUniqueArg("mtmsg_id", mtMessage.Id);
log.Println("EMAIL SEND: MTDEFSET: ", mtMessage.Id ); // Type of Id field on struct is: Id string json:"id";

Sendgrid's response showed no "mtmsg_id" key, and they said their logs don't have the unique arg on the message at that time.

Should I try setting the unique arg map directly? Why might this only happen some of the time?

from sendgrid-go.

Okay, we've found this happens only when there is a return character (which gets encoded by url.Values to %0A) in the subject line.

Thank you for being responsive on this issue.
