I have a problem to call graphql query. In Body sending as: { “query”: "query($first:Integer, $lastCursor:String, $catalogueRef: String!){ variantProducts(catalogue: {ref: $catalogueRef}, first:$first, after:$lastCursor){ pageInfo{ hasNextPage } edges{ cursor node{ product{ name } ref status attributes{ name type value } } } } } , “variables”: { “first”:10, “lastCursor”: null, “catalogueRef”:“COMPATIBILITY:1” } } But receiving below error: com.wm.app.b2b.server.ServiceException: com.wm.util.coder.InvalidDatatypeException: [ISC.0076.9012] Invalid state. JSON input stream does not start with the “{” character.
