Thanks, are you referring to the setting up the [request signature](https://docs.rapyd.net/build-with-rapyd/reference/message-security#request-signatures)?

Or would this be regarding, [GitHub - Rapyd-Samples/accept-payments: Explore top payment methods to learn how you can build with Rapyd in a single integration offering customers their preferred local payment features.](https://github.com/Rapyd-Samples/accept-payments)?

The GIH hub example

> **[accept-payments/nodejs at main · Rapyd-Samples/accept-payments](https://github.com/Rapyd-Samples/accept-payments/tree/main/nodejs)**
>
> main/nodejs

I cloned the code and I have added .evn with these variables

NODE\_ENV  
RAPYD\_ACCESS\_KEY  
RAPYD\_SECRET\_KEY  
PORT

When I try to debug using visual code on mac with m1 chip I get this error…

nodemon] app crashed - waiting for file changes before starting…

Hi @castle, confirming with our solutions engineer, this does happen with NodeJS in general. However, it doesn’t have anything to do with the repo nor the code. Sometimes it may be having 2 instances of node running a the same time.

> I usually just kill the node processes in the OS and restart VSCode, but again it wouldn’t have to do with the repo.

Here is a similar answer to a post in Stack Overflow.
