Internal Error 500: Running any snippet will cause an error

Describe the bug

I used the command ‘dotnet try --verbose’ and the site started up. But if I run any code snippets on the website, I get an error:

[MLS.Agent.Middleware.ExceptionFilter] ? System.NotSupportedException: Unsupported log file format. Latest supported version is 7, the log file has version 9.

Did this error occur while using dotnet try or online?

• dotnet-try
• online

What kind of error was it?

• User Interface (UI): For example the output never displayed
• Service Error: For example “The service is temporarily unavailable. We are working on it”
• Other:

@colombod Thanks! I tried the newer version and it’s working now.

But I think it still has some bugs.

Please look at the GIF:

When I run a snippet, a red block will be displayed if the file ‘package_fullBuild.binlog’ is not in the directory (./snippets). Wait until the file is generated and everything is fine.

Looks like that the binlog generation is in flight when you attempt the first run. Looks like a race condition to address
