Clickhouse: Can't parse data type from complex expression

[ultram4rine]

Before you file an issue

• Make sure you specify the "read" dialect eg. parse_one(sql, read="spark")
• Make sure you specify the "write" dialect eg. ast.sql(dialect="duckdb")
• Check if the issue still exists on main

Fully reproducible code snippet
Please include a fully reproducible code snippet or the input sql, dialect, and expected output.

ct = """Tuple(
        arr1 Array(String),
        arr2 Array(Tuple(c1 String, c2 Int64)
        )"""
exp.DataType.build(dtype=ct, dialect="clickhouse")

raise ParseError(f"No expression was parsed from '{sql}'")
sqlglot.errors.ParseError: No expression was parsed from 'Tuple(
        arr1 Array(String),
        arr2 Array(Tuple(c1 String, c2 Int64)
        )'

However, this works:

ct = """Tuple(
        arr1 Array(Tuple(c1 String, c2 String)),
        arr2 Array(Tuple(c1 String, c2 Int32)))"""
exp.DataType.build(dtype=ct, dialect="clickhouse")

STRUCT<arr1 ARRAY<STRUCT<c1 TEXT, c2 TEXT>>, arr2 ARRAY<STRUCT<c1 TEXT, c2 INT>>>

My actual data type is a lot more, like Tuple(DateTime64(3, 'UTC'), Int64, Nullable(String), String, ..., Array(Tuple(String, Int64, Nullable(String), ...)), Array(Tuple(...))), so I've tried to locate the problem

Sorry, messed out with brackets

Yeah, the input is invalid.
