Nhat Nguyen 4ecc7dcca5 Avoid StackOverflowError if write circular reference exception (#54147)
We should never write a circular reference exception as we will fail a 
node with StackOverflowError. However, we have one in #53589. 
I tried but failed to find its location. With this commit, we will avoid 
StackOverflowError in production and detect circular exceptions in
tests.

Closes #53589
