Cannot read properties of undefined (reading 'numTables') thrown during electrification of Capacitor adapter #756

Closed ccapndave closed 9 months ago

ccapndave commented 9 months ago

After updating to Electric 0.8, we get this error during the call to electrify (using the Capacitor plugin):

process.js:7 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'numTables')
    at he._verifyTableStructure (process.js:7:19)

I see the problem.

I've misunderstood the documentation for Capacitor SQLite's run method: <!DOCTYPE html> values any[] values when RETURNING

The adapter's exec() method should instead map to Cap-SQLite's query() method.

I'll make a PR shortly.

I'm closing this as we've merged https://github.com/electric-sql/electric/pull/760 which addresses this issue.
