[Event stream does not exists](https://twenty-v7.sentry.io/issues/7238297246/events/441b3c0465cf475a8349c7dec40cae2a/?environment=prod&environment=prod-eu&project=4507072499810304&query=is%3Aunresolved%20%21issue.type%3A%5Bperformance_consecutive_db_queries%2Cperformance_consecutive_http%2Cperformance_file_io_main_thread%2Cperformance_db_main_thread%2Cperformance_n_plus_one_db_queries%2Cperformance_n_plus_one_api_calls%2Cperformance_p95_endpoint_regression%2Cperformance_slow_db_query%2Cperformance_render_blocking_asset_span%2Cperformance_uncompressed_assets%2Cperformance_http_overhead%2Cperformance_large_http_payload%5D%20timesSeen%3A%3E10&referrer=previous-event&sort=date) Error happens when we are trying to add a query to a non-existing event stream. In some cases, this is legit. Stream has expired and needs to be re-created. Then we try to add the query again. But it should happen only once per tab, and not often. We have a lot of errors in sentry for each users. Potential root cause: a race condition between the event stream creation and the addition of queries: - event stream id is created in frontend state + creation query is sent - event stream id is in state so query can be added - addQuery happens before the stream is actually created in redis. So an error is returned - the error makes the event stream re-generated by frontend - => the flow starts again until the event stream is actually created BEFORE the first query is added Fix: a new state saying if event stream is ready - event stream id is created in frontend state BUT ready state is falsy so query is not added yet - on stream creation on backend side, an initial event is sent, so the frontend knows the stream is ready - addQuery can be triggered safely

Does the world need another CRM?
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in Open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
