I solved this one myself, but I don’t understand why it happened, and it might help the team so I am sharing. **Config:** - I am self hosting using a vultr VM - Ubuntu 16.04 - nginx 1.10.3 - Ghost 1.24.1 (production mode) - MySQL Ver 14.14 Distrib 5.7.22 - using the latest Casper theme **Background if it matters:** - I recently upgraded to 1.24.1 from 0.11. - Fresh install on a new VM. - Configured nginx myself with my own ssl crt and key - Exported data from old blog, imported in new. **Steps that lead to the error** - Install is done. Website is confirmed up. Ghost is working. - Ghost Admin: Settings:Apps:Slack is not configured. I am not using it so I left this unconfigured. - Created a new post using GhostAdmin on a laptop (web browser, normal web app). Edited team member pages. Edited bad markdown on imported posts. - Everything is fine. All working as expected. - Using ghost app on android phone: create a new post with an image. - Post fails to publish but informs me that it saved locally - Check admin panel via web browser on laptop and confirm that new post is there and unpublished - I try to publish it there and it fails with that red banner: `Can not find property 'url' of undefined.` - using ghost-cli I check the logs and see 500 errors on the PUT request for the post. - `core/server/services/slack.js` is identified in the stack trying to send a ping request. **How I solved It** - I insert a `return` at the top of the function `ping(post)` in `core/server/services/slack.js` - I restart ghost. - Create post. Publish. - Success _My Guess_ getSlackSettings is returning an undefined object because I did not configure slack. ---

Thank you. I wonder why this suddenly started happening. ---

Can you remember if you made any other changes with the mobile app or the desktop client? Other than that, if you don’t mind: could you double check the value of the slack setting in your JSON import file? I noticed that if the slack value get’s set to an empty array, this error occurs. But i was unable to reproduce it. Thanks for any help! ---

Before this bug showed up, I didn’t make any changes to the mobile app nor ghost’s code on the server. I transitioned over to ghost v1 from 0.11 on Friday. Made a test post with success. Then on Saturday tried to post via the mobile app. ---

> [@Kate](#): > > could you double check the value of the slack setting in your JSON import file? Sorry for ignoring this. I didn’t save the import file. So I can’t dig into the JSON. I’m browsing in mysql (command line which I am not good at) … app\_settings is empty apps is empty settings has a line for slack with key ‘slack’ value ‘’ ---
