@grammy/conversations v1.1.1 session parse error

[sc0ch]

Reprocude:

import { Bot, session } from "grammy"
import { conversations, createConversation } from '@grammyjs/conversations'
const token = 'XXXXXXXXXXXXXXXXXXXXXXX'
const bot = new Bot(token)
function initial() {
return { }
}
bot.use(session({ initial }))
bot.use(conversations())
let c = async function (conversation, ctx) {
await ctx.reply("Some message");
const { message } = await conversation.waitFrom(ctx.from)
console.log(message)
}
bot.use(createConversation(c))
bot.on('message', ctx => {
ctx.conversation.enter('c')
})
bot.start()

After any message to bot i've got:

/data/____/node_modules/@grammyjs/conversations/out/conversation.js:357
if (session.conversation[id].length === 0) {
^

TypeError: Cannot read properties of undefined (reading 'length')

@grammy/conversations v1.0.3 - have not that issue.

Could you format the source as TypeScript code and not as a heading?

Do you use a storage adapter?

You're missing an await when you enter the conversation. This is incorrect. Does adding this await fix the problem already?

[sc0ch]

Yep... forgot await, sorry.
False issue, please close it.

You're not the first one to forget this. I'll think about how to detect and prevent such mistakes library-side. Glad it's fixed!
