error with spq_label after adding skos:preflabel

[maelle]

spq_init(endpoint = "hal") %>%      
    spq_add("?labo skos:prefLabel ?labo_label") %>%
    spq_add("?labo dcterms:identifier ?labo_id", .required = FALSE) %>% 
    spq_filter(str_detect(labo_label,"EVS|(UMR 5600)|(Environnement Ville Soc)")) %>%
    spq_perform()

works.

I have been trying a few things with that but can't seem to get anywhere. I haven't managed to use an argument .languages=NULL in spq_label which you implied you had implemented in Discord (and which is a possibility according to the documentation of spq_label).

The query:

spq_init() %>%      
  spq_add("?labo dcterms:identifier ?labo_id.") %>% 
  spq_label(labo, .required = TRUE,.languages=NULL) %>%
  spq_filter(str_detect(labo_label,"EVS")) %>% 
  spq_head(10)

returns a similar error
