GAMLSS ERROR : NA's in the working vector or weights for parameter mu

I am getting the following error ERROR : NA's in the working vector or weights for parameter mu for the gamlss function: fit <- gamlss::gamlss(x ~ y, sigma.formula = ~ y, data = d, family = GA)

where d is a dataframe containing x and y

x = 17.83961 29.73269 14.15842 15.00793 35.53764 13.53545 17.13169 35.67923 14.68229 10.59050 13.73367 26.58952 21.33674 28.60002 36.24556 22.00219 30.2990326.50457 28.17526 41.05943 19.22714 37.09507 24.32417 21.29427 23.72952 23.72952 18.37763

what is the cause of this error?

Maybe it is related to the data. If you swap x and y, a model will come out:

fit <- gamlss(y ~ x, sigma.formula = ~ x, data = d, family = GA)
