Redash Version: 25.1.0

Environment:

• Self-hosted
• MongoDB data source

Issue Summary:
After upgrading to Redash v25.1.0, queries that reference cached query results (such as query_XXX tables created from MongoDB sources) fail with the following error:

Error running query: Error binding parameter 0 - probably unsupported type.

Direct MongoDB queries run successfully without errors, but when cached query results (query_XXX) are used, even simple queries consistently fail.

Steps to Reproduce:

1. Create a MongoDB aggregation query and save results as a cached query (query_XXX).
2. Attempt to execute a simple SQL query against the cached result, e.g.:

SELECT * FROM query_XXX LIMIT 10;

1. Observe the error.

MongoDB Aggregation Example Causing Issue:

{
  "collection": "devices",
  "aggregate": [
    { "$match": { "cr_time": { "$gt": { "$humanTime": "2024-01-01 00:00" }}, "msisdn": { "$type": 2 }}},
    { "$project": { "cr_time": 1, "msisdn": { "$toString": "$msisdn" }, "client": { "$toString": "$client" }}}
  ]
}

Expected Results:
Queries referencing cached MongoDB results execute without errors.

Actual Results:
Queries referencing cached MongoDB results fail consistently with:

Error running query: Error binding parameter 0 - probably unsupported type.

Attempted Workarounds (unsuccessful):

• Explicitly casting fields to strings in MongoDB ($toString, $convert).
• Creating intermediate SQL tables with explicit type casting.
• Restarting Redash services.

Additional Information:

• Direct queries to MongoDB execute successfully.
• Error occurs only when referencing cached query results.

Request:
Please investigate the underlying issue with cached query result handling from MongoDB in Redash v25.1.0.
