Got error when using data.table in qmd code

[iMissile]

I'm trying to make snapshot from command line with cmd webshot2::rmdshot("test.qmd", file = "tst.png") an got error

Error in :=`(value, gear + carb) : Check that is.data.table(DT) == TRUE. 
Otherwise, := and :=(...) are defined for use in j, once only and in particular ways. 
See help(":=")

Rendering the same file in RStudio or through rmarkdown::render I've got correct .html file.

I suppose that it's caused by absense of data.table @ Import section in DESCRIPTION.
Finding reasons here:

• https://cran.r-project.org/web/packages/data.table/vignettes/datatable-importing.html
• https://stackoverflow.com/questions/27980835/r-data-table-works-in-direct-call-but-same-function-in-a-package-fails
• https://stackoverflow.com/questions/10527072/using-data-table-package-inside-my-own-package/10529888#10529888

Sample qmd sile:

library(data.table)
library(kableExtra)
library(webshot2)

data <- mtcars
df <- setDT(data)[, value := gear + carb][, .(mpg, value)]

kable(df)
