bwr_query_create and bwr_query_delete not working

[dklinenberg2020]

Code being run:

brandwatchR::bwr_auth(un = "XXXX",
                      pw = "XXXX")

my_projects <- bwr_projects_get()
head(my_projects)

(my_project <- bwr_projects_get()$id)

(my_query <- bwr_query_get(project_id = my_project)$id)


bwr_query_create(project_id = my_project,
                 samplePercent = 50,
                 includedTerms = 'at_mentions:mickeymouse',
                 name = 'test1')

output:

Error in bwr_query_create(project_id = my_project, samplePercent = 50,  : 
  Bad Request (HTTP 400).

No issues until I run bwr_query_create.
