Upgrading Airbyte breaks the webapp with 'baseUrl is invalid'

TL;DR

For "baseUrl is invalid": upgrade to the latest Airbyte Helm chart. Set airbyteUrl and INTERNALAPIHOST correctly in your values file.

baseUrl is invalid

Steps

1. The problem: you upgraded Airbyte (in this case 0.64.6 to 0.79.0) with Helm and the webapp wont load, showing "baseUrl is invalid". Your data and connections are fine; this is the Helm chart's URL handling, not a data problem.
2. Upgrade to the latest Airbyte Helm chart. Airbyte staff noted this specific error was fixed in later chart versions, so a chart upgrade is the supported path, not a config hack.
3. Set airbyteUrl and INTERNALAPIHOST correctly in your values file. Double check for stray trailing slashes or old-format values carried over from the pre-upgrade values file; those leftovers are the usual trigger.
4. Apply the upgrade with the corrected values and reload the webapp. The reporter who hit this confirmed it was resolved on the newer chart.
5. If the error persists after the chart upgrade, diff your values file against the chart's current values template and remove anything the new chart no longer expects.

The thread asked why the Airbyte webapp failed to load with "baseUrl is invalid" after upgrading from 0.64.6 to 0.79.0 with Helm.
