Hi!
I'm currently scripting an authentication application. The authentication is performed by using an electonic ID on a mobile device (e.g. an iPhone). The users enters his/her ID-number on a web page and then opens the ID security application on the mobile device and enters a pin-code. During this time the web page continuosley polls the server for status of the authentication.
I've recorded this flow using LR 11.52, and LR successfully records the poll and adds a web_reg_async_attributes step to the script. But when I try to replay (with added parameters) the replay fails with an error that is unknown to me.
Below is the code for the poll recorded by LR (web_add_header and web_sync steps added manually):
web_reg_async_attributes("ID=Poll_0",
"Pattern=Poll",
"URL=https://XXXXXX/login/ajax/poll",
"PollIntervalMs=1600",
"RequestCB=Poll_0_RequestCB",
"ResponseCB=Poll_0_ResponseCB",
LAST);
web_add_header("X-CSRF-TOKEN", lr_eval_string("{CSRF}"));
web_add_header("Accept", "application/json");
web_add_header("X-Requested-With", "XMLHttpRequest");
web_add_header("Accept-Language", "sv");
web_add_header("Connection", "Keep-Alive");
web_custom_request("poll",
"URL=https://XXXXXX/login/ajax/poll",
"Method=POST",
"TargetFrame=",
"Resource=0",
"RecContentType=application/json",
"Referer=https://XXXXXX/login/poll",
"Snapshot=t9.inf",
"Mode=HTML",
"EncType=application/json",
LAST);
web_sync("ParamCreated=authStatus", "RetryIntervalMs=800", "RetryTimeoutMs=60", LAST);
web_stop_async("ID=Poll_0", LAST);
During replay the scipt fails with the following error message
AH_Testverktyg.c(136): Warning -26499: Internal Error - Invalid mptTaskItem=073B8C00 / _ptConversInfoItem=00000000 / Pattern=[Invalid] (NOT repetitive) / ID="" (IsValid=0) / UrlCrack IsValid=1 for URL="https://XXXXXX.se/login/ajax/poll" in RequestToRepeat CTOR for this=06666C60 [MsgId: MWAR-26499]
AH_Testverktyg.c(136): Error -35050: Parameter 'authStatus' was not defined and the time to wait for it has elapsed. This timeout can be set by passing argument 'RetryTimeoutMs' or by changing 'web_sync retry timeout' in Run-Time Settings. [MsgId: MERR-35050]
Notable is that the first poll works.
Also, when I modify the script and use a for-loop instead, the script works fine, so I don't think there is any problem with the actual request being sent. In this case it works fine with the for-loop since nothing needs to be executed during the poll, but I think the LR-poll function is a more neat solution :-)
Has anyone encounter this and managed to get it to work?
Best Regards!
