What causes it

v6 removed transp= (v5 only hid it). Transparency now goes inside the colour.

The fix, compiled

Delete transp= and pass the transparency to color.new(): 0 is opaque, 100 is invisible.

Prints the error at line 4

//@version=6
indicator("My script")
ma = ta.sma(close, 20)
plot(ma, color = color.blue, transp = 70)

Compiles with no error

//@version=6
indicator("My script")
ma = ta.sma(close, 20)
plot(ma, color = color.new(color.blue, 70))
