Facing an issue in getIntradayContinuousEPEXSPOT() function!

I am running a code provided in the readme file and it's giving me this error.

`prices <- getIntradayContinuousEPEXSPOT("2020-01-01", "2023-08-18", "60", "CH")`

Error: 

Error in seq.default(1, length(times_list) - 1, 7) : 
  wrong sign in 'by' argument
