https://ethereum.stackexchange.com/questions/144949/compiler-error-stack-too-deep
I am getting this error when trying to deploy my smart contract using zkSync but on a different chain (Polygon Mumbai):
CompilerError: Stack too deep. Try compiling with `--via-ir` (cli) or the equivalent `viaIR: true` (standard JSON) while enabling the optimizer. Otherwise, try removing local variables.
