Exception Code: 142 crashes due to (0xE0434352 - CLR Exception)

This issues is usually because of the worker runtime setting

Mismatched worker runtime setting - (0xE0434352 - CLR Exception) function internal server error

I has this issue once. As it turned out was FUNCTIONS_WORKER_RUNTIME in application settings set to dotnet, although I am quite sure that I opted for javascript. Correcting the value to "node" solved the problem.

Please ensure in your web app , you runtime is correctly set.
