Getting API error occurred: account_inactive when using Slack Postmessage api to send message to slack user

Question

I am building a slack app that would send messages to user. Recently I am getting an error which says "account_inactive". The slack documentation describes the following error as below

Authentication token is for a deleted user or workspace when using a bot token.

I tried sending a message to a deactivated slack user using "chat.postMessage" using a bot token "xoxb-token" and the API returns success all the time. It would be great if anyone can help me with what causes this error.

PS: I am not using BoltJS, I am using he JS SDK directly.

Answer 1

Sounds like your app has been uninstalled from the workspace. You can try calling auth.test to see if the token is still valid.

Answer 2

I've come across this error recently.

In my case, the cause was that when a user account is deactivated, some apps they've installed are also deactivated. If this is the case for you, a member with the permission to manage apps will need to reactivate it.
