Sentry plugin - Variable value in dashboard report an HTTP 400 "Invalid project parameter"

[JeSappelleRoot]

What happened:

I'm trying to use variable to define project name on my Sentry dashboard as referenced on the documentation of the plugin
https://grafana.com/grafana/plugins/grafana-sentry-datasource/

What you expected to happen: Filter error with the project name from the defined variable

How to reproduce it (as minimally and precisely as possible):
Add Sentry as datasource and use variable as project filter with the following parameters :
Query type : Stats
Project : your variable name (from the drop-down menu)
Field : sum(quantity)
Category filter : error

Anything else we need to know?:

Sentry Grafana integration is based on the following documentation https://grafana.com/grafana/plugins/grafana-sentry-datasource/
Also, permissions on Sentry end are the following :
Project : read
Team : no access
Release : no access
Issue & Event : read
Organization : read
Member : no access

Environment:

• Grafana version: 8.4.0
• Data source type & version: Sentry plugin
• OS Grafana is installed on: Ubuntu 20.04
• User OS & Browser: Firefox 96
• Grafana plugins: Sentry
• Others:

When I'm performing filtering with drop down menu, here the JSON

From query inspector without variable

{
  "request": {
    "url": "api/ds/query",
    "method": "POST",
    "data": {
      "queries": [
        {
          "datasource": {
            "uid": "lcd6BkB7k",
            "type": "grafana-sentry-datasource"
          },
          "environments": [],
          "hide": false,
          "projectIds": [
            "10"
          ],

As you can see, projectIds is set to 10, which is the right value on Sentry side for the project (from the URL e.g)

From query inspector with variable

{
  "request": {
    "url": "api/ds/query",
    "method": "POST",
    "data": {
      "queries": [
        {
          "datasource": {
            "uid": "lcd6BkB7k",
            "type": "grafana-sentry-datasource"
          },
          "environments": [],
          "hide": false,
          "projectIds": [
            "${sentry_project}"
          ],

As you can see, with variable from dashboard, the syntax is correct but I have the following result
"error": "400 Bad Request Invalid project parameter. Values must be numbers."
The variable seems correct according to the documentation

I also tried to replace project name with an integer as value but no luck with the following variable configuration :
Variable type : custom
Values separated by comma : my-project:10

Some help will be appreciated

Thank you for your report.

After investigating the issue further, I can see that we are not currently interpolating variables when used in the Projects field. This is a known issue, and we have an issue already in the Sentry datasource repo to address this.

I'm closing this issue in favour of the issue in the Sentry datasource repo.
