The 10 Most Common Bubble Errors and How to Fix Every One

Every Bubble builder hits the same walls. The workflow that should fire doesn’t. The repeating group that should show data shows nothing. The condition that should be true evaluates to false. These are not random bugs — they are predictable errors with predictable solutions. This guide documents the 10 most common, what causes them, and exactly how to fix each one.

10 Errors and Their Exact Fixes

Repeating group shows no data

Causes: (1) Privacy rule blocking the search — temporarily set all fields to “visible to everyone” to test. (2) Search constraint is too restrictive — remove constraints one by one until data appears. (3) Data source uses the wrong data type — check the RG type matches the search type. (4) User is not logged in — check Current User exists. Fix privacy rules last; they are the most common culprit.

Workflow step doesn’t run

Cause: The “Only when” condition on the step evaluates to false. Use Bubble’s debugger (step-by-step mode) to inspect the exact value of every condition when the workflow runs. The condition is almost always comparing the wrong values — a common example is comparing a text field to a number or comparing an empty state to a populated field.

Page shows data from wrong workspace

Cause: A search is missing the workspace = Current User’s current_workspace constraint. Scans all records and returns any that match the other conditions. Add the workspace constraint as the first constraint on the search. Also check that current_workspace is set correctly on the User record after login.

Stripe webhook not triggering Bubble workflow

Causes: (1) Webhook URL in Stripe points to /version-test instead of production. (2) Bubble workflow is not set as “exposed as API endpoint”. (3) Stripe is sending to the wrong endpoint URL — copy the exact URL from Bubble’s API tab. Check Stripe’s webhook logs for the exact error it is returning.

Custom state resets unexpectedly

Cause: Custom states on an element reset when the element is rerendered. If the element’s visibility condition changes (it hides and reshows), its states reset. Move the state to the Page element instead — page states persist for the entire session regardless of element visibility changes.

API call returns empty or errors

Causes: (1) Parameter name mismatch — the API expects email but the call sends Email (case sensitive). (2) Private key not set as “private” in API Connector — it is not being sent. (3) API requires JSON body but Content-Type header is missing. Check the raw request and response in Bubble’s API Connector “Initialize” panel.

Navigation doesn’t work after workflow action

Cause: “Navigate to page” step has an “Only when” condition that evaluates to false. Or the step is conditional on a previous step’s result that failed. Use step-by-step debugger to confirm each step executes. Also check the destination page exists and the URL is spelled correctly.

:count always returns 0

Cause: Privacy rules are blocking the search — count() respects privacy rules. The search returns 0 because no records pass the privacy check for Current User. Test by temporarily making the data type visible to everyone. If count increases, fix the privacy rule to correctly allow the search.

Condition “is not empty” evaluates incorrectly

Cause: Bubble distinguishes between a field being empty (null) and a field containing an empty string (“”). An input field that a user clears may contain “” rather than null. Use is not empty AND :count > 0 for lists, or use :trimmed is not empty for text inputs to handle both null and empty string cases.

Search is slow on pages with lots of data

Cause: Using :filtered by anywhere in the search. This loads all records client-side before filtering. Replace every :filtered by with a search constraint. Also check for deep relational chains in RG cells (Cell’s record’s parent’s grandparent) — each hop is a separate database query per row.
