When the MongoDB server returns an IllegalOperation error (code 20), the NODE driver reports a misleading message:

> await db.createCollection('system.buckets.foo');
Uncaught:
MongoServerError: This MongoDB deployment does not support retryable writes. Please add retryWrites=false to your connection string.

Even for errors completely unrelated to retryWrites, end even if already using --retryWrites=false (which does not matter anyway).

Expected Behavior

As a... Node Driver user
I expect... to see actual server message
When... server returns an IllegalOperation error

Actual Behavior and Impact

• What is the actual behavior?
• If bug: What is the number of impacted customers? How severe is the impact? Is anyone blocked or broken?
• The actual behavior: hard-coded error text "This MongoDB deployment does not support retryable writes. Please add retryWrites=false to your connection string.", which is not at all correct.
• Bug: Unknown number of impacted customers. This bug has been in the codebase for a while now.

Dependencies

• None

Risks/Unknowns

• Risk: actual error text makes it back to caller.
