TS99001
Maximum nesting depth exceeded; the rest of this construct was skipped.
ts-r stopped descending into very deeply nested code to avoid running out of stack. Split the nested expression or type.
What it means
This is a ts-r code; tsc doesn't have it. ts-r's parser and binder limit how deeply they recurse into nested expressions, types and statements, so that pathological input produces a diagnostic instead of a stack overflow. When the limit is reached, the rest of that construct is skipped and this error is reported. Real code almost never gets close; it usually comes from generated files with thousands of nested parentheses, arrays or binary operators.
How to fix
- Restructure the generated code so it nests less: build long chains in a loop or split them into several statements.
- If ordinary code triggers it, report it as a bug with the file.
