Wierd error when using request logger

1

We’re getting an odd error when request logging is turned on, has anyone seen anything like this before?

TargetInvocationException Exception has been thrown by the target of an invocation.

Haven’t seen that before but that should be prevented with this commit which is available from v5.0.3 that’s now available on MyGet.

Looks like this fixed it, thanks!

Just to add a bit more here. That seemed to initially fix it, but we then noticed that any large responses would just cause the endpoint to timeout. Not entirely sure right now if these went hand in hand as we had not been testing larger requests (MB in size - like a PDF download). It seems to be due to writing the response DTO as part of the log. We’ve since disabled response DTO logging for now until we can investigate further.
