= note: please follow the instructions below to create a bug report with the provided information
= note: for incremental compilation bugs, having a reproduction is vital
= note: an ideal reproduction consists of the code before and some patch that then triggers the bug when applied and compiled again
= note: as a workaround, you can run cargo clean -p test_zone_sdk_e2e or cargo clean to allow your project to compile
