Hello everybody!

I’m receiving a 500 error, with no more details. The app runs with no error or warning but when I try to deploy this happen:

Hi Maximiliano,

Can you please tell me if you have deployed an app before? Are you deploying from a local environment or via a CI/CD pipeline, and have you checked if you have the necessary permissions? Is there a same app already deployed? There might be various reasons for it, so once you can provide me with more details I’ll try to help out.

Hi&nbsp;[@haris](https://community.dynatrace.com/user/57428)&nbsp;,  
Yes, I’ve deployed several times before and I’m deploying from a Local Env., and yes there’s another version of this app installed already, I’m using WSL.

Hello&nbsp;[@haris](https://community.dynatrace.com/user/57428)&nbsp;  
Yesterday in the end of the evening I tried again and it was a success. I don’t really know what happened with our Tenant, or something, but is working again.

I appreciate your help,&nbsp;[@haris](https://community.dynatrace.com/user/57428)!  
Thanks,  
Maximiliano Lopes
