Contexts are not sending sometime

[rahulghodke191090]

why contexts(uuid) is not being sent with queryText sometimes from android ? I checked dialogflow history Raw interaction log, Weird behaviour :( below is my request code block

window["ApiAIPlugin"].requestText({query: message, contexts : [ { name: "uuid", parameters: { uuid: this.deveiceuuid } }] },async(response) => { console.log(response) }, (error) => { console.log(JSON.stringify(error)); // to pupup messages });
