MethodError: no method matching preprocess_data(::DataFrame, ::Symbol, ::Symbol, ::Symbol, ::Nothing, ::Symbol, ::Bool)

What does this error mean? can someone kindly help to resolve this.

Can you please post the function that you are calling, preferable a MRE?

Can you also post the full error message?

pop1 = read_pumas(merodata1, observations = :dv,
id=:id,
time=:time,
amt=:amt,
rate=:rate,
cmt=:cmt,evid=:evid)

I am calling “read_pumas” function

Full error message:

It should be observations = [:dv]
observations takes a vector, not a symbol.

pop1 = read_pumas(merodata1, observations = [:dv],
id=:id,
time=:time,
amt=:amt,
rate=:rate,
cmt=:cmt,evid=:evid)
