Fiware wirecloud widget upload: error no valid parser found

Question

I want to create a widget and upload it to my FIWARE Mashup Workspace. When I upload my ".wgt" file I get the error:

Error adding packaged resource: Error parsing config.xml descriptor file: No valid parser found.

How can I get more information about the error? Is it simply a parsing error, or is something different went wrong (no valid parser found sounds like some service is missing)

Is there a way to check my config.xml file?

Answer 1

This is definitely a configuration error; there is no service missing. Since your config is in xml, check it with an XML checker, to be sure that no opening/closing tags are missing.

If your wgt is an operator, check that your preferences/endpoints have different IDs. Also, please be sure that all your endpoints use distinct names
