I'm getting an error in the backoffice when I try to look at the log files using log viewer.

Here is the entry in the log file (I've trimmed it a bit)

as it is a test site, I've reinstalled it and it is now working without errors.
One difference is that the first time I ran the first site, I did it through IIS Express in VS2017, but for my second attempt, I first ran it as a site set up on a Windows Server 2012.
Thanks for your assistance.
Its' probably not necessary to send you the log file now ...
I got a copy from Seb and the JSON is malformed on line 71 of the file that you sent him
{"@t":"2019-03-01T14:31:36.6433405Z","@mt":"{LogPrefix} Waiting for tasks to complete","LogPrefix":"[HealthCheckNot{"@t":"2019-03-01T14:31:49.0573244Z","@mt":"{StartMessage} [Timing {TimingId}]","StartMessage":"Booting Umbraco 8.0.0 on NPT-162663.","TimingId":"7d0bd70","SourceContext":"Umbraco.Core.Runtime.CoreRuntime","ProcessId":13024,"ProcessName":"iisexpress","ThreadId":23,"AppDomainId":5,"AppDomainAppId":"LMW3SVC2ROOT","MachineName":"NPT-162663","Log4NetLevel":"INFO ","HttpRequestNumber":1,"HttpRequestId":"b137d16f-9e5c-4d09-a25a-86cf549f5fba"}
In here you can see the problem in LogPrefix"LogPrefix":"[HealthCheckNot{"{"@t":"2019-03-01T14:31:49.0573244Z",
It has a new log item entry inside the health check one.
Can you please confirm every time you try this with your repro steps above, you get the same/error problem with malformed JSON and I would be curious to know if it's the same error with the log item HealthCheck.
Unfortunately we're unable to reproduce the problem on our machines. For now we'll assume it's something on your machine, not sure what else we could look into.
Maybe you can zip up the whole site that is giving you the log errors and send it over https://wetransfer.com/ so I can check if there's anything weird. Make sure to zip it up with a strong password (30 characters at least) and send me the zip password in a separate message.
Error in backoffice Settings section
I'm getting an error in the backoffice when I try to look at the log files using log viewer.

Would it be possible to share the whole log file so we can debug? You can send it to [email protected] if you want.
Hi Sebastiaan

Please, if you still have it, this looks like a bug we need to fix one way or another :)
Sebastiaan
I had deleted the site in order to reinstall it, so I created another just like the one that failed, and yes, I have got the same errors.
I will send you the log file.
Thanks

Hi Maurice
As you were able to reproduce this error/bug again then can you please give me some insight and in-depth details on how you reproduced it.
Thanks,

Hi Warren
I'm using Microsoft Visual Studio Professional 2017 (Version 15.9.7).
These are the steps I took in VS 2017,
In VS 2017, I selected the option "IIS Express (Internet Explorer)" to run the project.
Then in the backoffice settings section, I hit the problem above when using the log viewer.
I have emailed a copy of the log file to Sebastiaan.
(Note that when I ran the site for the first time after setting it up on the Windows Server 2012, rather than IIS Express, I didn't hit this problem).
Many thanks
Muiris

Hi Warren
I've just sent today's log file to Sebastiaan, after trying to view the log files in the backoffice.
Shall I try building a completely new site again, or do as I've just done, and log into the one which failed last Friday?
thanks
Maurice

the clue was staring at me all along.
The problem was running the site for the first time in VS 2017 using IE 11 (version 11.590.17131.0 to be precise).
I tried it in Chrome and Edge and there weren't any problems.
However, if I removed the log file and launched the site in IE 11, it hit the problem again.
So, it looks like an IE problem (which I guess I shouldn't use anyway).
Would you still like a zipped up version of the site?
Thanks

Hi, I have the exact same error on Azure, any ideas ? Thank you
