i have tried running a workshop example ( Problem 1: Simulate a first-order absorption model with linear elimination after a 100 mg oral dose in 24 subjects)

i am getting error in this part  
Part 2: Perform a model fit

```auto
res = fit(mymodel,data,param,Pumas.FOCEI())
single_dose_regimen = DosageRegimen(100, time=0)
first(single_dose_regimen.data)

s1 = Subject(id=1, evs=single_dose_regimen,cvs=(Wt=70,))

choose_covariates() = (Wt = rand(55:80),)

pop = Population(map(i -> Subject(id = i,evs = single_dose_regimen, cvs = choose_covariates()),1:24))

mymodel = @model begin
  @param begin
    tvcl ∈ RealDomain(lower=0, init = 1.0)
    tvv ∈ RealDomain(lower=0, init = 20)
    tvka ∈ RealDomain(lower = 0, init= 1)
    Ω ∈ PDiagDomain(init=[0.09,0.09, 0.09])
    σ_prop ∈ RealDomain(lower=0,init=0.04)
  end

  @random begin
    η ~ MvNormal(Ω)
  end

  @pre begin
    CL = tvcl * (Wt/70)^0.75 * exp(η[1])
    V = tvv * (Wt/70) * exp(η[2])
    Ka = tvka * exp(η[3])
  end
  @covariates Wt

  @dynamics OneCompartmentModel
    #@dynamics begin
    # Depot' = -Ka*Depot
    # Central' = Ka*Depot - (CL/V)*Central
    #end

  @derived begin
      cp = @. 1000*(Central / V)
      dv ~ @. Normal(cp, sqrt(cp^2*σ_prop))
    end
end

param = init_param(mymodel)

obs = simobs(mymodel, pop, param, obstimes=0:1:72)
plot(obs)

simdf = DataFrame(obs)
first(simdf, 6)

simdf.route = "ev"

timeu = u"hr"
concu = u"mg/L"
amtu = u"mg"

ncadf = read_nca(simdf, id=:id, time=:time, conc=:cp, amt=:amt,
    route=:route,timeu=timeu, concu=concu, amtu=amtu, lloq=0.4concu)

plot(ncadf)

auc = NCA.auc(ncadf)

cmax = NCA.cmax(ncadf)

report = NCAReport(ncadf)
report = NCA.to_dataframe(report)
first(report,6)

simdf.cmt = ifelse.(ismissing.(simdf.cmt), 2, simdf.cmt)
est_df = simdf[.!((simdf.dv .== 0.0) .& (simdf.cmt .==2)),:]
first(est_df,6)

data = read_pumas(est_df ,cvs = [:Wt], dvs=[:dv])

res = fit(mymodel,data,param,Pumas.FOCEI())

```

Hi Sai,

Can you post what’s the error that you are getting?

I’m unable to reproduce this. Which version of Pumas and JuliaPro are you using. Also, does the error persist if you rerun the program?

Which version of Pumas are you using? You can see it if you write `] status` or `Pkg.status()`.

You are not using the latest version of Pumas. Could you please try `] up Pumas` or `Pkg.update("Pumas")` and then restart Julia and rerun your code?
