getObservation SweDataArrayValue' is not yet supported!

[oggioniale]

I obtain a warning message while trying to get observations from the SOS I am using for the Italian network of the European infrastructure eLTER-RI.

The SOS responds to sosURL = "http://getit.lteritalia.it/observations/service".
My code is:

> mySos <- sos4R::SOS(
    url = sosURL,
    binding = "POX",
    useDCPs = FALSE
  )
> offerings <- sos4R::sosOfferings(mySos)
> offering <- offerings[[1]]
> obs <- sos4R::getObservation(
      sos = mySos,
      offering = offering@id,
      procedure = sos4R::sosProcedures(offering)
    )
Warning message:
In .handleExceptionReport(sos, response) :
  Object of class OwsExceptionReport; version: 1.1.0; lang: NA;
 1 exception(s) (code @ locator : text):
  NoApplicableCode @ NA :
	The merging of value type 'org.n52.sos.ogc.om.values.SweDataArrayValue' is not yet supported! 

The obs object is:

> obs
Object of class OwsExceptionReport; version: 1.1.0; lang: NA;
 1 exception(s) (code @ locator : text):
  NoApplicableCode @ NA :
	The merging of value type 'org.n52.sos.ogc.om.values.SweDataArrayValue' is not yet supported! 

When try to convert observations to results:

> results <- sos4R::sosResult(obs, coordinates = TRUE) %>%
      tibble::as_tibble()
Warning message:
In .local(obj, coordinates, ...) :
  OwsExceptionReport does not have a result set.

How can solve it?

You are receiving an exception from the server, as far as I see. You may change the response format.

[oggioniale]

how? What do you suggest?

@EHJ-52n thanks!!

the response formats supported are:

> sos4R::SosSupportedResponseFormats()
[1] "text/xml;subtype=\"om/1.0.0\""       "text/xml;subtype=\"sensorML/1.0.1\"" "text/csv" 

I try to execute the getObservation for each of the three formats.

      sos = mySos,
      offering = offering@id,
      procedure = sos4R::sosProcedures(offering)
    )

For deeper details, we might ask @nuest or @BenGraeler to give us more details, why the allowed response formats are not working.

[oggioniale]

👍🏽 thank you, I wait the feedback from @nuest and @BenGraeler

Someone have comments about this issue?

Otherwise I need to take a different way to obtain the results for the SweDataArrayValue types.
