I\'ve deployed a nodejs app running on the Google App Engine Flex runtime using the following app.yaml configuration:
runtime: nodejs
env: flex
I don't have a solution to the root problem. But if the spamming is making it impossible to use the log for its intended purpose, like it is for me, here is a work around:
Enable the 'Advanced Log Filters' (the tiny down arrow next to the search field in Stackdriver Logging)
Add this to the Search query
NOT textPayload : (health)
