broadcast_model concatenation error

[Huta2018]

The following error arose when I run this code

phis = broadcast_model(
# Fit with two components, a linear background, and a Lorentzian peak
[AffineBackgroundModel, LorentzianModel],
# fit across the entire near_ef dataset
near_ef,
# fit along each value of "temperature"
"temperature"
)

TypeError: can only concatenate tuple (not "list") to tuple
