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

[49470952]

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.
