Parsing error was not very useful

[jay-jlm]

Hi,

I got the error below, which lookes to me like graphql was trying to output a useful parsing error but failed to do so.
After a lot of trial and error I eventually narrowed it down to being a mutation declaration that did not specify any parameters

/Users/joao/node_projects/my-server/node_modules/graphql/error/syntaxError.js:28 var error = new _GraphQLError.GraphQLError('Syntax Error ' + source.name + ' (' + location.line + ':' + location.column + ') ' + description + '\n\n' + highlightSourceAtLocation(source, location), undefined, source, [position]); ^ GraphQLError at syntaxError (/Users/joao/node_projects/my-server/node_modules/graphql/error/syntaxError.js:28:15) at expect (/Users/joao/node_projects/my-server/node_modules/graphql/language/parser.js:966:32) at parseName (/Users/joao/node_projects/my-server/node_modules/graphql/language/parser.js:88:15) at parseInputValueDef (/Users/joao/node_projects/my-server/node_modules/graphql/language/parser.js:743:14) at many (/Users/joao/node_projects/my-server/node_modules/graphql/language/parser.js:1015:16) at parseArgumentDefs (/Users/joao/node_projects/my-server/node_modules/graphql/language/parser.js:735:10) at parseFieldDefinition (/Users/joao/node_projects/my-server/node_modules/graphql/language/parser.js:714:14) at any (/Users/joao/node_projects/my-server/node_modules/graphql/language/parser.js:1002:16) at parseObjectTypeDefinition (/Users/joao/node_projects/my-server/node_modules/graphql/language/parser.js:683:16) at parseTypeSystemDefinition (/Users/joao/node_projects/my-server/node_modules/graphql/language/parser.js:607:16)

I wonder if this could be improved somehow to provide a better debugging experience, thanks!

That is indeed not very useful. How were you invoking the parser to obtain this output?

Thanks for responding.
I was running a Node (FeathersJS) server.

Should be fixed by #718
