error message when only 1 number is used as a constraint

Session Info

It would be helpful to have a more explicit error message reminding users to pass a vector of length 2 for each constraints. When only 1 number is passed, the error message is confusing:

library(rerddap)

ERDDAP_Node <- "https://coastwatch.pfeg.noaa.gov/erddap/"
dataInfo <- rerddap::info('jplMURSST41', 
                          url=ERDDAP_Node)

var <- dataInfo$variable$variable_name
date1="2014-01-01"

dat <- griddap(
  url=ERDDAP_Node, "jplMURSST41",
  time = date1,
  latitude = c(41.01585, 44.6308),
  longitude = c(-72.41734, -65.96161),
  fields = var[1]
)

gives this error message:
Error: Error {
code=500;
message="Internal Server Error: Error: destinationVariableName=analysed_sst2014-01-01 wasn't found in datasetID=jplMURSST41.";
}
