cannot read property 'data' undefined

Question

I am trying to get ag-grid row data for editing in a modal window. during render vue throughs the bellow error.

[Vue warn]: Error in mounted hook: "TypeError: Cannot read property 'data' of undefined"

my code. This is the mounted method.

mounted() {
    this.leadsData = JSON.parse(JSON.stringify(this.params.data))
},

how are you passing the data you want to retrieve? If you are using route parameters you need to use this.$route.params.data — Timo

this.params must be a variable present in the data function, otherwise, if you look for a property in the url you can use this.$route.params.data or this.$route.query.data
