Dashboard Import issue (with expression as datasource)

Grafana Dashboards
1

We are trying to move few Dashboard from one Org to another. In most of the Dashboards, we have we have used Expressions. We are facing issue to importing these exported json file. Error: _expr , No Data Sources Found.

Part of json file:
{
“inputs": [
{
“name”: “DS_CCI-NVCL”,
“label”: “cci-nvcl”,
“description”: “”,
“type”: “datasource”,
“pluginId”: “graphite”,
“pluginName”: “Graphite”
},
{
“name”: "DS___EXPR”,
“label”: “expr”,
“description”: “”,
“type”: “datasource”,
“pluginId”: “expr”
}
],
“__elements”: ,
“__requires”: [
{
“type”: “datasource”,
“id”: “expr”,
“version”: “1.0.0”
},
{
“type”: “grafana”,
“id”: “grafana”,
“name”: “Grafana”,
“version”: “8.3.3”
},
{
“type”: “datasource”,
“id”: “graphite”,
“name”: “Graphite”,
“version”: “1.0.0”
},
{
“type”: “panel”,
“id”: “stat”,
“name”: “Stat”,
“version”: “”
},
{
“type”: “panel”,
“id”: “timeseries”,
“name”: “Time series”,
“version”: “”
}
],

How to overcome this issue?

datasource on org 1 might match datasource on org 2 by name only but not by uid so on dashboard being imported the datasource uid needs to match datasource uid in org 2

      "datasource": {
        "type": "mssql",
        "uid": "0saGbrE4k"
      },

Thanks for your reply. But I can’t see any this type of id in json file.
“inputs": [
{
“name”: “DS_CCI-NVCL”,
“label”: “cci-nvcl”,
“description”: “”,
“type”: “datasource”,
“pluginId”: “graphite”,
“pluginName”: “Graphite”
},
{
“name”: "DS___EXPR”,
“label”: “expr”,
“description”: “”,
“type”: “datasource”,
“pluginId”: “expr”

later it has been used as:
“datasource”: {
“type”: “graphite”,
“uid”: “${DS_CCI-NVCL}”
},

Eevn when I export one similar dashboard from org2, the jexported file is similar to it. Looks like the expr is creating issue. Because while importing, user _expr field showing “No Data Sources found”.
