error in calcAnchors

[ishwar97]

Hi @midraed, Greetings!
I sometimes face this error while using calcAnchors function:

hot.and.cold <- calcAnchors(image = image.TOAr, Ts = Ts, LAI = LAI, plots = TRUE, albedo = albedo, Z.om = Z.om, n = 1,
anchors.method = "flexible", deltaTemp = 5, verbose = FALSE)
Error in apply(x[i, ], 1, which.min) : dim(X) must have a positive length

I don't exactly know how to solve this issue. Please have a look at this and help me through.
Thank you!
