Hi @PARKER-X! I wasn't able to load your screenshot, but based on your description — SQL Lab not working after creating a new Superset folder with a different SECRET_KEY — this is most likely caused by a SECRET_KEY mismatch.

The most likely culprit: SECRET_KEY mismatch

When you create a second Superset instance with a different SECRET_KEY, the new instance cannot decrypt credentials (database connection passwords, session tokens) that were encrypted with the original key. This causes SQL Lab to fail, often with misleading error messages that hide the real problem [1].

Steps to try:

Clear your browser cookies/session for the Superset URL and log in fresh to the new instance — stale session cookies from the old key will be rejected.
Re-create your database connections in the new Superset instance. Don't reuse connections that were created with the old SECRET_KEY, since the stored passwords are encrypted with that key and can't be decrypted by the new one.
Use a consistent SECRET_KEY — don't change it between restarts of the same instance. If you need to rotate it, Superset provides a superset re-encrypt-secrets CLI command to re-encrypt stored credentials with the new key.
Check the Superset server logs (not just the browser error) — the full traceback will show the actual failure point.

Could you share the exact error message you're seeing in the browser or in the Superset logs? That would help pinpoint the exact issue much faster.

@PARKER-X — the error ValueError: Invalid decryption key is coming from sqlalchemy_utils's EncryptedType, which Superset uses to encrypt database connection credentials stored in the metadata database. It means the SECRET_KEY currently in use doesn't match the one that was used when those credentials were originally saved [1].

Since you mentioned "in this folder I am using my old key and it works before," something is causing Superset to pick up a different key now. Here's what to check:

Verify SECRET_KEY in your config — open your superset_config.py and confirm the key value is exactly what you originally used. Watch out for trailing spaces, newlines, or encoding differences.
Check for environment variable override — if SUPERSET_SECRET_KEY is set as an environment variable, it will override your config file. Run echo %SUPERSET_SECRET_KEY% in your terminal to check.
Confirm superset_config.py is actually being loaded — Superset logs Loaded your LOCAL configuration at [...] on startup [1]. Check your startup logs to make sure it's picking up the right file.
Don't rotate the key without re-encrypting — once you restore the original key, things should work again. If you genuinely need to change the key, you'd need to decrypt all stored credentials with the old key and re-encrypt with the new one first.

Once you confirm the correct SECRET_KEY is in place, restart Superset and try again.

The TypeError: Cannot convert undefined or null to object is a frontend React crash — a component is receiving null or undefined where it expects an object, and the entire page crashes at the error boundary.

The minified stack trace makes it hard to pinpoint the exact component, but this type of crash has occurred in SQL Lab before — for example, when error payload fields like error.extra.sql were unexpectedly null [1], or when a host shell export like useAppDispatch was undefined at runtime [2].

Without more context (e.g. what page or action triggered this), here are some things to try:

Clear browser state — open DevTools → Application → Local Storage → http://127.0.0.1:8088 and clear everything, then hard-refresh. Stale cached state (SQL Lab tabs, query history) can cause render crashes if the data shape doesn't match what the current version expects.
Clear cookies/session for 127.0.0.1:8088 and log in fresh.
Check the backend logs — the Python server logs when the page loads will often reveal the real problem (a missing config value, a decryption error, etc.). The frontend crash is just a symptom of the data it received.

To help narrow this down further, could you share:

Your Superset version (pip show apache-superset)
What page/action triggers the error (SQL Lab? Dashboard? Chart?)
Any Python-side error logs from the same timeframe
