Possibly resolved by the `.gitignore` update in https://github.com/UniversalRobots/PolyScopeX_URCap_SDK/commit/96b0435716623e66ab33298f7e257bd262266530#diff-bc37d034bad564583790a46f19d807abfe519c5671395fd494d8cce506c42947

In the [nodejs client](https://docs.powersync.com/client-sdk-references/node), I use [`waitForFirstSync()`](https://powersync-ja.github.io/powersync-js/node-sdk/classes/AbstractPowerSyncDatabase#waitforfirstsync). Maybe it will work for your tests ```ts const powerSync = new PowerSyncDatabase({ ... }); await powerSync.connect(...); await powerSync.waitForReady(); await powerSync.waitForFirstSync(); ```
