WalkthroughThis change replaces the previous encrypted message content type with a new union type across message and attachment definitions, updates the chat.update REST params to accept encrypted content and e2e mentions, adjusts decryption to populate message text, and updates editMessage to handle encryption and branch requests accordingly.

83-107: Consider a single discriminated union without the base interface.Defining
TEncryptedContentdirectly tightens thealgorithmliteral type and reduces indirection. Current approach works; this is just simplification.export type TEncryptedContent = | { algorithm: 'rc.v1.aes-sha2'; ciphertext: string } | { algorithm: 'rc.v2.aes-sha2'; ciphertext: string; iv: string; kid: string };

Add fallback for servers that don’t support content in chat.update.
Currently, edits in E2EE rooms may fail on older servers (where text is required). Try content first, then fallback to text with the ciphertext.
export const editMessage = async (message: Pick<IMessage, 'id' | 'msg' | 'rid' | 'content' | 'e2eMentions'>) => {
const result = await Encryption.encryptMessage(message as IMessage);
if (!result) {
throw new Error('Failed to encrypt message');
}
if (result.content) {
- // RC 0.49.0
- return sdk.post('chat.update', {
- roomId: message.rid,
- msgId: message.id,
- content: result.content,
- e2eMentions: result.e2eMentions
- });
+ try {
+ // Prefer new API with encrypted content
+ return await sdk.post('chat.update', {
+ roomId: message.rid,
+ msgId: message.id,
+ content: result.content,
+ e2eMentions: result.e2eMentions
+ });
+ } catch (e) {
+ // Fallback for older servers: send ciphertext as text
+ const ciphertext = (result as any).msg ?? result.content.ciphertext ?? message.msg ?? '';
+ return sdk.post('chat.update', {
+ roomId: message.rid,
+ msgId: message.id,
+ text: ciphertext
+ });
+ }
}
// RC 0.49.0
return sdk.post('chat.update', {
roomId: message.rid,
msgId: message.id,
text: message.msg || ''
});

I tested it on the Mobile workspace (7.9.0), and editMessage doesn’t work, encryptMessage always returns content and fails on chat.update.
