Forest plot for Multistate Cox proportional hazards model.

Hi,
I would like to create a forest plot for a multistate cox model but I found several errors. This is the code:

data3$Age <- factor(data3$Age, levels = c("2", "3","4","5","6","7","1","8"), labels = c("0-19", "20-29","30-39","40-49","50-59","60-69","70-79","over 80"))

data3$Age = relevel(data3$Age, ref = "70-79")

cfit5 <- coxph(Surv(tstart, tstop, event) ~ Age, data=data3, id=ID_PER)
print(cfit5)

ggforest(cfit5, data = data3, main='Hazard ratios')

The print(cfit5) returns:

Call:
coxph(formula = Surv(tstart, tstop, event) ~ Age, data = data3, 
    id = ID_PER)

 States:  1= (s0), 2= altro ricovero, 3= intensiva 

Likelihood ratio test=1658  on 21 df, p=< 2.2e-16
n= 18823, number of events= 1524 

The result of the model is good but then when I try to create the forest plot I obtain:

Errore in axisTicks(rangeb/2, log = TRUE, nint = 7) : 
  log - axis(), 'at' creation, _LARGE_ range: invalid {xy}axp or par; nint=7
	 axp[0:1]=(1e-307,1e+308), usr[0:1]=(0,inf); i=615, ni=87
In aggiunta: Messaggi di avvertimento:
1: In min(x) : nessun argomento non-mancante al minimo; si restituisce Inf
2: In max(x) :
  nessun argomento non-mancante al massimo; si restituisce -Inf

Can someone help me? Thank you
