Error messages

Installation

Q: I get the following error message when trying to run sudo:
  sudo: sorry, you are not allowed to set the following environment variables: PERL5LIB

A: You seem to be having restricted full sudo rights. See deploying for more info.

Visualization

Q: The WMS client fails to show any images, and Log4JS reports the following error:
    FATAL - Invalid GetMapContext: TypeError: maxExtent is null

A: This rather cryptic error is OpenLayers complaining about having no background layer. Check that you have a background map available in the specified projection.

Transformation

Q: I'm getting the following error in the log:
    ERROR: no coordinate-systems with projection found, maybe you should try coordinate interpolation in CDMInterpolator.cc at line 488
    exception occured: CDMException: no coordinate-systems found

A: Your FIMEX version is out of date. Use 0.41 or later which supports selectVariables.
