Invoke-RestMethod parallel problem #15513
Description
Steps to reproduce
It happens randomly. Most of the time it works. Sometimes it fails and no other Invoke-RestMethod is possible after.
1..10 | ForEach-Object -Parallel { Invoke-RestMethod -Uri "www.google.com" -Headers @{
"method"="GET"
"scheme"="https"
}
} -ThrottleLimit 3
Expected behavior
To work everytime without the concurrent update error.
Actual behavior
Sometimes it returns the error bellow, and no further Invoke-RestMethod is possible in the session (it always returns the very same error) :
Invoke-RestMethod: Operations that change non-concurrent collections must have exclusive access. A concurrent update was performed on this collection and corrupted its state. The collection's state is no longer correct.
