error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/AleoHQ/leo/issues/new?labels=bug,panic&template=bug.md&title=[Bug]

note: leo-lang 1.6.3 running on Linux 5.15.90.1-microsoft-standard-WSL2

note: compiler args: leo build

note: compiler flags: CLI { debug: false, quiet: false, command: Build { command: Build { options: BuildOptions { offline: false, enable_spans: false, enable_dce: false, enable_all_ast_snapshots: false, enable_initial_input_ast_snapshot: false, enable_initial_ast_snapshot: false, enable_unrolled_ast_snapshot: false, enable_ssa_ast_snapshot: false, enable_flattened_ast_snapshot: false, enable_inlined_ast_snapshot: false, enable_dce_ast_snapshot: false } } }, api: None, path: None }

Expected Behavior

Throw some error saying that the transition should have some test_credits as output.
