possible network issue warning

[gsalin]

Hi,
I upgraded from OTRS 6.0.29 to znuny 6.5.1 (with znuny 6.1, 6.2, 6.3 and 6.4 upgrades in between).
We encounter a strange behaviour (non blocking) which is reproducible.

If we open a ticket, create an answer : if we delete an email address in the To or Cc field, we get the following message in a popup :
Znuny detected possible network issues. You could either try reloading this page manually or wait until your browser has re-established the connection on its own
If we reload the page clicking on the corresponding button of the popup, the deleted email address appears again (seems normal), if we click on "Close this dialog" button, we get the folowwing message fw seconds later :
The connection has been re-established after a temporary connection loss. Due to this, elements on this page could have stopped to work correctly. In order to be able to use all elements correctly again, it is strongly recommended to reload this page.
here is a gif showing this behavior

Any idea what can cause this behavior?

Thank you for your help

the message "The connection has been re-established after a temporary connection loss. Due to this, elements on this page could have stopped to work correctly. In order to be able to use all elements correctly again, it is strongly recommended to reload this page." appears when I type 2 letters in the "To" or "Cc" field...not after few seconds in fact

in dev tools of the browser, there are no javascript error, nor network issues......

System log?

[gsalin]

thanks for the reply
nothing appears in system log when I get this warning, nor in the otrs.log on the server

[gsalin]

better, inserted debugger and console.log

I find :
TargetNS.ApplicationError ErrorMessage Error during AJAX communication. Status: parsererror, Error: SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

I keep go on debug

usefull dev tools!!

watched for control and xhr events.
clicking on the minus icon (a#RemoveCustomerTicket_1.RemoveButton.CustomerTicketRemove) to remove an email address, an xhr call is done, with a status code 200.
looking at its content, shows some nteresting lines :

Insufficient Rights
Message: No Permission to use this frontend module!

the xhr request which seems to cause the error is : Action=RS_AdminCustomerUser2&Subaction=GetNewButton&ChallengeToken=XXXXX


any idea for what can cuase this issue?

[gsalin]

looking at the code server side, the faulty code is from a package RS4OTRS_NewCustomerFromTicket-6.0.1
so no bug from znuny
I will check if there is a more recent version....

Great you figure it out..
Do you have 3rd party addon installed?
Something regarding customer user?

I dont think RS_AdminCustomerUser is part of the default znuny / otrs

[gsalin]

yes RS4OTRS_NewCustomerFromTicket-6.0.1
we wrote at the same time
