error when exporting smartdocs model

[sidd-harth]

Hi guys, when I'm trying to export a model in WADL file type from smart docs I'm getting this error,

"There was an error exporting the ‘ecomm test’ model."

While Export file type-SmartDocs JSON works fine.

Note- I made the model by manually creating resources and methods. Can this be a reason I cannot export it in WADL format?
