Database error after update from 19.0.7 to 20.0.5

After update to 20.0.5 the status page tell me that I must call:

occ db:convert-filecache-bigint

because this 3 tables must converted:

federated_reshares.share_id
share_external.id
share_external.parent
But the php ./occ db:convert-filecache-bigint run fails with:
In SchemaException.php line 85:

There is no column with name ‘auto_id’ on table ‘oc_files_trash’.

What can I do?
In the occ tool, I don’t have find an “schema check” or something.

As an workaround, because the table was empty:

show create table oc_files_trash;
drop table oc_files_trash;
run occ db:convert-filecache-bigint
CREATE TABLE oc_files_trash (
id varchar(250) COLLATE utf8mb4_bin NOT NULL DEFAULT ‘’,
user varchar(64) COLLATE utf8mb4_bin NOT NULL DEFAULT ‘’,
timestamp varchar(12) COLLATE utf8mb4_bin NOT NULL DEFAULT ‘’,
location varchar(512) COLLATE utf8mb4_bin NOT NULL DEFAULT ‘’,
type varchar(4) COLLATE utf8mb4_bin NOT NULL DEFAULT ‘’,
mime varchar(255) COLLATE utf8mb4_bin NOT NULL DEFAULT ‘’,
KEY id_index (id),
KEY timestamp_index (timestamp),
KEY user_index (user)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin ROW_FORMAT=COMPRESSED;

And now no messages about table needs maintenance.
