Question: How to send encrypted custom events?

[jaller94]

I'm trying to send encrypted events, but only standard messages are successfully sent. Not custom events like this:

client.sendEvent(roomId, 'org.matrix.msc3672.beacon', {
    "m.relates_to": { // from MSC2674: https://github.com/matrix-org/matrix-doc/pull/2674
        "rel_type": "m.reference", // from MSC3267: https://github.com/matrix-org/matrix-doc/pull/3267
        "event_id": beaconEventId,
    },
    "org.matrix.msc3488.location": {
        uri: lastPosition.geo,
        // description: "Arbitrary beacon information"
    },
    "org.matrix.msc3488.ts": Date.parse(lastPosition.date),
});

I get the following error:

thread '<unnamed>' panicked at 'Encrypting an event produced an error: JsonError(Error("Failed to serialize event [content] enum: Unknown event type.\nTo send custom events, turn them into `Raw<EnumType>` by going through\n         `serde_json::value::to_raw_value` and `Raw::from_json`.", line: 0, column: 0))', crates/matrix-sdk-crypto-nodejs/src/machine.rs:330:14
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
fatal runtime error: failed to initiate panic, error 5
./run.sh: line 10: 52386 Aborted                 (core dumped) npx ts-node src/index.ts

I've tried to make content safe by wrapping it like this: JSON.stringify(content) and JSON.parse(JSON.stringify(content)). However, so far nothing change the error.

[turt2live]

arg, this looks like ruma being slightly awkward to work with.

[jaller94]

Affects:

• 0.6.0-beta.7 and likely previous versions
• 0.6.0-beta.8

[turt2live]

it'll affect all 0.6.0 versions until the bindings are fixed. There is no timeline on that at present.

[turt2live]

This will be fixed by new bindings: https://github.com/turt2live/matrix-bot-sdk/pull/236
