Login error for users with '+' in their account names

[fsallstrom]

Hi, I have many users getting login error. All of them have a + in their dexcom username. I know it used to be a problem before to have sepcial characters in the username but that was fixed long time ago. either there was some change in the dexcom API that cause these accounts to fail authentication, or I am doing something wrong with the character encoding of my login requests.

This request works:
curl -k -X POST https://shareous1.dexcom.com/ShareWebServices/Services/General/AuthenticatePublisherAccount --data '{"password":"<hidden password here>", "applicationId":"d89443d2-327c-4a6f-89e5-496bbb0317db", "accountName":"[email protected]"}' -H "Accept: application/json" -H "Content-type: application/json"

but if I try with another account that has a + in their dexcom username, like this:
curl -k -X POST https://shareous1.dexcom.com/ShareWebServices/Services/General/AuthenticatePublisherAccount --data '{"password":"<hidden password here>", "applicationId":"d89443d2-327c-4a6f-89e5-496bbb0317db", "accountName":"+14087977776"}' -H "Accept: application/json" -H "Content-type: application/json"

I get an error message:
{"Code":"AccountPasswordInvalid","Message":"Publisher account password failed","SubCode":"<OnlineException DateThrownLocal=\"2023-06-27T15:33:08.793\" DateThrown=\"2023-06-27T15:33:08.793Z\" ErrorCode=\"AccountPasswordInvalid\" Type=\"13\" Category=\"4\" Severity=\"1\" TypeString=\"InvalidPassword\" CategoryString=\"Validation\" SeverityString=\"Minor\" HostName=\"\" HostIP=\"\" Id=\"{b2963c4a-0429-4ca2-af79-d5fc1ee4c3b4}\" Message=\"Publisher account password failed\" FullText=\"com.dexcom.udp.common.data.exception.OnlineException: Publisher account password failed\" />","TypeName":"FaultException"

Both account works fine when logging into https://uam1.dexcom.com

Any ideas?

Still have not been able to resolve the issue with account names including '+' being rejected by the dexcom server. Here is what I get in the Heroku log file:

2023-07-14T21:17:26.611383+00:00 app[web.1]: Cannot authorize account: null 500 {
2023-07-14T21:17:26.611407+00:00 app[web.1]: Code: 'AccountPasswordInvalid',
2023-07-14T21:17:26.611407+00:00 app[web.1]: Message: 'Publisher account password failed',
2023-07-14T21:17:26.611411+00:00 app[web.1]: SubCode: '',

I have also tried using curl to post the request directly, but with the same results. It seems like there is an issue with the dexcom server (only tested the US one), very similar to the previous issue with special chars in the acount name that later got fixed.
