Win32Exception thrown on idle

[mclausen]

Which Umbraco version are you using? (Please write the exact version, example: 10.1.0)

13.0.0-rc3

Bug summary

Running the back office locally on OSX causes the back office to throw an exception.

Unexpected exception in TimingPipeFlusher.FlushAsync.
 ---> System.ComponentModel.Win32Exception (14): Bad address

This is a fresh install, where I created 1 document type, 1 content node and published the content node. I am unsure whether this information has anything to do with it 🤔..

After creating, my back office has been idling for some time, before it started to throw an exception.

Specifics

Steps to reproduce

I do not know how to reproduce. The back office is running idle on my local machine (running osx).. The exception is being thrown multiple times

Expected result / actual result

No exception...

I am not using a dev certificate when running locally, that might be connected 🤔

Thanks for reaching out @mclausen 👋

I tried it on my machine and it works fine for me 🙂 As we discussed, you managed to make it work with the help of dotnet dev-certs command 💪

I will go ahead and close this
