Charts with GAM trend line that are created in older releases can fail for scheduling at the server

If you have published content (such as a chart, note, slide, dashboard) that contains a chart with trend lines created in Exploratory Desktop version 6.0.2 or earlier version, you may see a scheduling failure like the following when you schedule it.

Error: Error in vapply(x, asJSON, character(nrow(x)), collapse = FALSE, complex = complex,  : 
  values must be length 40,
 but FUN(X[[3]]) result is length 1

You can fix it by republishing it again from Exploratory Desktop 6.0.3 or later version.
