Queries on Dashboard don't show results/graphs correctly

[drixsus]

Issue Summary

When refreshing queries/dashboards manually, we see queries are executed according to the backend logs. However, the process never seems to end or if they do, the graphs likely remain empty. seeing the logs in the server, neither errors nor query activity is seen.

Steps to Reproduce

Not sure about the steps to reproduce it. We've just migrated Redash from 25.1.0 to 25.8.0 recently. It's worth noticing that we didn't have this issue in the version 25.1.0.

We use Mongo Atlas DB v8.0.15 as datasource for the graphs. we´ve made several checks, it is just working.

I attach what we see in browser's logs

as a side note of the screenshot, the query has data to show and should've drawn a pie graph

Technical details:

• Redash Version: v25.8.0
• Browser/OS: Chrome/Linux
• How did you install Redash: docker compose as suggested in getredash/setup repository

Any suggestion to address this issue is welcome

Thanks in advance

Thank you for you report !

I'm not sure for now.
But, how about clicking "Test Connection" in the Data Source settings to check the connection ?

[drixsus]

@yoshiokatsuneo thanks for answering. it actually works, I mean the connection to our database is ok and it brings results. I've been looking through this doc and tweaking some env vars, with no luck yet

How about setting environment variable REDASH_LOG_LEVEL=DEBUG and check worker container docker logs ?
I think you'll get logs like "mongodb got query: %s", for example .

Also, following information might be helpful

• Is the issue happens only on MongoDB data source ? (ex: "Query Result" data source)
• Can you run simple query like below (replacing "YOUR-COLLECTION-NAME" to your collection.) ?

{
    "collection": "YOUR-COLLECTION-NAME",
    "limit": 10
}

thanks for following it up @yoshiokatsuneo. We appreciate

we've had to move backward our redash version to 25.1.0.

Just answering your questions

• MongoDB is the only datasource we have so far
• yes, the query runs
