Hello all,  
I am facing issue where I keep seeing warning as below and I'm not sure where I went wrong.

```python
05:23:31.243 [Browser Thread: f02d1639-9f88-4868-9a26-750f49e65b5b] WARN Perspective.Designer.Workspace -- level: WARNING
message: "crbug/1173575, non-JS module files deprecated."
line_number: 6587
source: "chrome-error://chromewebdata/"

```

I am using Ignition 8.1.39 and project is created in Perspective Module.  
Any help is appreciated and let me know if any more data is needed

This happened after an upgrade? ...or just started happening for no clear reason?

No, we have not performed any upgrade, application was developed and deployed at different servers but Ignition version was kept at v8.1.39.  
Since It does not affect any operation (as far as I know), we have been able to work without an issue.
