CREATE TABLE xxx.table1 (
  name1 STRING COMMENT '',
  sb_col STRUCT<id: STRING, ss_col: ARRAY<MAP<STRING, STRUCT<c: INT, d: STRING>>>>)
USING iceberg

alter table xxx.tbale1 RENAME COLUMN sb_col.ss_col.element.value.d to d_1;

Error in query: Field name sb_col.ss_col.element.value.d is invalid: sb_col.ss_col.element is not a struct.; line 1 pos 0

After trying, error is reported when the ARRAY and MAP of the nested fields are directly next to each other.
For example, ARRAY<MAP<STRING, STRUCT<x: INT>>> or MAP<STRING, ARRAY<STRUCT<x: INT>>> , changing the name of field x will result in an error: Error in query: Field name xxx is not a struct

If the ARRAY and MAP of the nested fields are not directly next to each other, like ARRAY<STRUCT<a: MAP<STRING, STRUCT<x: INT>>>> , changing the name of field x will not result in the error above.
