Entity share PULL Entities issue

$context['resource_type'] is set in entity_share/modules/entity_share_client/src/Service/JsonapiHelper.php from the return value of ResourceTypeRepository->getByTypeName()

This will return null if a resource type is not found with that name.

Just showing the user which name returned null, and possibly a list of valid names, would go a long way to helping debug what the underlying issue is.

E.g.

if (!$resourceType instanceof ResourceType) {
  $allTypes = $this->resourceTypeRepository->all();
  $args = [$data['type'], implode(', ', array_keys($allTypes))];
  throw new \InvalidArgumentException(vsprintf('ResourceType with name %s not found. Valid names are: %s', $args));
}

After I added this code when when syncing entities that fail I now get an error like:

ResourceType with name node--region not found. Valid names are: batch_plugin_entity--batch_plugin_entity, block--block...
