Plotting a bar plot with text as the xaxis gives me an error where it didn’t use to. I’m using Julia 1.4 and plots v1.0.5

plot([“a”,“b”],[10,2],yerr=[1,1],st=:bar) gives the error “Cannot `convert` an object of type String to an object of type Float64” listed at the bottom.  
plot([“a”,“b”],[10,2],st=:bar) gives no error and plots as I would expect.  
If I change to plots V1.0.4 it still doesn’t work but if I go back to v1.0.0 they both work as normal.

Anyone else experience this?

MethodError: Cannot `convert` an object of type String to an object of type Float64
