Betabin suddenly not accepting midyear population as n

[Fredrick orwa]

Dear Statalist members has something change in betabin model with any new updates? The last time I ran the command in my stata it accepted decimal for midyearpopulation.Today its displaying error in the same dataset. see below
betabin count_ipd if serotype=="1", n(midyrpopn_ipd) link(cloglog)
N() must be a positive integer expression that is >= the outcome
r(199);
