[BUG]: Slack Piece's Send message to a channel action does not show a list of channels

[Gaket]

Describe the bug
Slack Piece's Send message to a channel action does not show a list of channels and doesn't work as a result.

To Reproduce
Steps to reproduce the behavior (seems to be Slack-connection specific):

1. Create a new flow
2. Add a Slack piece v0.5.6 or v0.5.7
3. Set Send to channel action
4. Connect to a Slack account
5. Open the Choose a channel list
6. Wait for loading
7. See the "Throws an error, reconnect or refresh the page" error

Expected behavior
There is a list of different channels to send messages to

Screenshots
This is how it looks like:

Permissions were given:

Additional context

I have another Slack workspace and a personal ActivePieces account where it works well.

I have tried to delete and set the Slack connection again on the work account, it didn't help.

Other actions:
"Send message to a user" - work well
"Request approval in a channel" - errors out the same way.

I looked at the response of piece-slack request, looks like the permissions are fine:

"auth": {
        "description": "",
        "authUrl": "https://slack.com/oauth/v2/authorize?user_scope=search:read,users.profile:write",
        "tokenUrl": "https://slack.com/api/oauth.v2.access",
        "required": true,
        "scope": [
            "channels:read",
            "channels:manage",
            "channels:history",
            "chat:write",
            "groups:read",
            "groups:write",
            "reactions:read",
            "mpim:read",
            "mpim:write",
            "im:write",
            "users:read",
            "files:write",
            "files:read",
            "users:read.email"
        ],
        "type": "OAUTH2",
        "displayName": "Connection"
    },

The error seems to be coming from the
https://cloud.activepieces.com/api/v1/pieces/options call:

{
    "disabled": true,
    "options": [],
    "placeholder": "Throws an error, reconnect or refresh the page"
}

The Active Pieces app was added to the required channel, it doesn't look like the issue is bound to it.

Hi! Is there any way I can help providing logs without deploying the app myself? I don't have much JS/TS experience, but I can try.

Hi @abuaboud!

Unfortunately, it didn't help. What I did:

1. Removed the piece
2. Went to connections, removed the connection
3. Created a new connection with a different name
4. Added the Slack piece (v 0.5.10)
5. Stil getting the same error

Just in case, the same issue persists with "Send a message" action when I try to select a channel:
