dfm Error in qatd_cpp_tokens_replace

[almogsi]

Describe the bug

quanteda::dfm() get's stuck in certain tokenized tweets. I'm getting:

"Error in qatd_cpp_tokens_replace(x, type, ids_pat, ids_repl) :
Not compatible with requested type: [type=NULL; target=double]."

Reproducible code

stucked_tweet <-  "@POTUS Lol too funny yes we're all tired of Jim #Acosta too President Trump Gets Angry At Jim Acosta of CNN… https://t.co/gzUw4PF4s8"
t <- tokens(tolower(stucked_tweet), remove_numbers = T, remove_punct = T, remove_url=T)
tt <- tokens_remove(t, pattern = "^@\\b", valuetype = "regex")
t.dfm <- dfm(tt, remove_twitter = T)
