Error 500: Internal Server Error Accessing a Web service

[didje007]

Hello,

I have an error 500: Internal Server Error when accessing a web service deployed with an executable on a PC without LabVIEW.

I develop my application in LabVIEW 2018, the webservices works fine on my development environment. It works fine on my development Machine in exe.

However when deployed on one machine as an exe. I have this error after one particular web service has been called 3 times.In the mean time other web services continue to respond. I have to stop my program (use the task manager because one process doesn't stop) and when restarted the web service will reply 3 times more.

I suspect the process which doesn't stop is linked to the web services but I haven't been able to find any confirmation. I have searched for log error files generated by the Web server but I haven't found any.

I have no idea where this error comes from aand how to correct it.

Since I had no reply to my previous message, I will formulate a more simple and generic question.

Is there a way to genereate error log from the embededd web server in an application?

I found how to change the level of verbosity of the appserver: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000019QK9SAM&l=fr-FR

But this log stays empty in my case since.

Best regards
