Fixes https://github.com/payloadcms/payload/issues/13433. Testing release: `3.54.0-internal.90cf7d5` Previously, when calling `getPayload`, you would always use the same, cached payload instance within a single process, regardless of the arguments passed to the `getPayload` function. This resulted in the following issues - both are fixed by this PR: - If, in your frontend you're calling `getPayload` without `cron: true`, and you're hosting the Payload Admin Panel in the same process, crons will not be enabled even if you visit the admin panel which calls `getPayload` with `cron: true`. This will break jobs autorun depending on which page you visit first - admin panel or frontend - Within the same process, you are unable to use `getPayload` twice for different instances of payload with different Payload Configs. On postgres, you can get around this by manually calling new `BasePayload()` which skips the cache. This did not work on mongoose though, as mongoose was caching the models on a global singleton (this PR addresses this). In order to bust the cache for different Payload Config, this PR introduces a new, optional `key` property to `getPayload`. ## Mongoose - disable using global singleton This PR refactors the Payload Mongoose adapter to stop relying on the global mongoose singleton. Instead, each adapter instance now creates and manages its own scoped Connection object. ### Motivation Previously, calling `getPayload()` more than once in the same process would throw `Cannot overwrite model` errors because models were compiled into the global singleton. This prevented running multiple Payload instances side-by-side, even when pointing at different databases. ### Changes - Replace usage of `mongoose.connect()` / `mongoose.model()` with instance-scoped `createConnection()` and `connection.model()`. - Ensure models, globals, and versions are compiled per connection, not globally. - Added proper `close()` handling on `this.connection` instead of `mongoose.disconnect()`. --- - To see the specific tasks where the Asana app for GitHub is being used, see below: - https://app.asana.com/0/0/1211114366468745
