Call to protected method StylePluginBase::renderFields() in views_merge_rows_views_pre_render()

Hi,

I am testing project Drupal Remote Dashboard 8.x-3.0 with Views Merge Rows 8.x-2.1 as dependent module. Some views are not generated with an error in the logs:

I think it is view merge role related.
Environment: server apache 2.4, php 7.1.2 and Drupal 8.3.0
