Changing the indexes of field storage with non revision entity is broken

Problem/Motivation

SqlContentEntityStorageSchema::updateDedicatedTableSchema() is broken when the entity type doesn't support revision.

The error message is:

TypeError: Argument 4 passed to Drupal\Core\Entity\Sql\SqlContentEntityStorageSchema::addIndex() must be of the type array, null given, called in /Project/web/core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorageSchema.php on line 1388 in Drupal\Core\Entity\Sql\SqlContentEntityStorageSchema->addIndex() (line 2102 of core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorageSchema.php).

I use the config_devel to update the field config file automatically. To adding indexes in field table, I add an item indexes into field.storage.registrant.field_my_field.yml. It looks like:

langcode: zh-hant
status: true
dependencies:
  module:
    - rng
id: registrant.field_my_field
field_name: field_my_field
entity_type: registrant
type: string
settings:
  max_length: 255
  is_ascii: false
  case_sensitive: false
module: core
locked: false
cardinality: 1
translatable: true
indexes:
  value:
    - value
persist_with_no_fields: false
custom_storage: false

Set the config file importing automatically in config_devel. I expect config_devel will import the config and add value (field_register_code_value) field as index in field_my_field database table. However, when the index is added or dropped, it will throw an exception as above.

Proposed resolution

Check if the entity type support revision or not.
