I’m trying to publish my custom component and am getting this error: ![Screen Shot 2022-02-02 at 12.43.39 PM](https://us1.discourse-cdn.com/flex020/uploads/adalo/original/2X/5/5f0cd062c266d2f0ac3e439ff7fe1cfade18cf59.png) It doesn’t seem like anyone else has experienced this. Also difficult to troubleshoot because there’s no explanation for the error. ^ this is after I run `npx adalo publish` ---

I get that often, most of the time it is caused by not running `npx adalo login` prior to publishing. If that does not solve the issue let me know and I can give some more guidance on debugging. ---

Okay, I just tried to publish a new component and I get undefined, but this time it is a bug in their CLI probably related to `Link to Demo App`. To fix this problem you need to roll back to an older version of the CLI. open package.json and find `"@adalo/cli": "0.0.48,"` and replace that with `"@adalo/cli": "0.0.42,"` after that run `yarn` to install the old version of the CLI and publish again. It will solve your issue ---

That’s weird, i was using `0.0.48` and publishing normally, but good to know ---

I was fine up until 10 minutes ago, then I got a 503 error. Reverting back to 0.0.42 let me publish. I think they are deploying changes to the component marketplace in preparation for Monday beta and they made a bug. Probably will be fixed later today, for now 42 works ---
