I’ve had a workflow working for 6+ months just uploading a graphic status to a slack channel but for the past two days the Slack File Upload node has stopped working. Send Slack messages is working without issues, it’s just the Slack File Upload has stopped working.
I’ve checked that the curl command of the API works ok - so it appears to be N8N file upload related ?
curl -F [email protected] -F "initial_comment=Test Curl File Upload" -F channels="#ignore-jka-channel" -H "Authorization: Bearer xoxb-SLACK-BOT-CRED" https://slack.com/api/files.upload
Slack node - returns: options.channelIds.join is not a function
This workflow was from the 1.2.1 (next) docker instance, but the same happens on 1.1.1.
- n8n version: Tried this on 1.1.1 and Postgres 1.2.1
- Database (default: SQLite): SQLite 1.1.1 , Postgres 1.2.1
- n8n EXECUTIONS_PROCESS setting (default: own, main):
- Running n8n via (Docker, npm, n8n cloud, desktop app): Docker self hosted
- Operating system: Redhat
