Error Message when using att_gt(): lapply(X = unname(split(e, grp)), FUN = FUN, ...) : invalid formal argument list for "function" #194

Hi, I ran into an error message from using did package, att_gt(). My code set up is as below:
out<-did::att_gt(yname="value", tname="month", idname="eci", gname="first.treated",

xformla=~matchto,

        data=dat3,
        control_group=c("nevertreated","notyettreated"),
        est_method = reg)

Error in lapply(X = unname(split(e, grp)), FUN = FUN, ...) : invalid formal argument list for "function"

this R code worked for a couple of times, but for some reason, it started to give me an error message now. I am not sure what caused this error (would it be caused by a specific did version?). Please can someone help me with this issue? Thank you very much in advance.

Thanks for reply, above is the subset of the dataset I use. Also, I used below code to install 'did' package:

devtools::install_github("bcallaway11/did") library(did)

Please let me know if you have any thoughts on solving this issue. Thank you very much.
