Hello! I could use your help. I am trying to use the custom code to update US phone numbers. I’m trying to use this code: [https://github.com/HubSpot/sample-workflow-custom-code/blob/main/samples/format\_phone.js](https://github.com/HubSpot/sample-workflow-custom-code/blob/main/samples/format_phone.js) Unfortunately I’m getting an authentication issue, even though I have the proper access to the API key. I’m wondering if I’m missing something. I would appreciate any insights or guidance. Thank you so much! Here is the error that I’m receiving: `2022-03-30T21:30:42.009Z ERROR Unhandled Promise Rejection {"errorType":"Runtime.UnhandledPromiseRejection","errorMessage":"HttpError: HTTP request failed","reason":{"errorType":"HttpError","errorMessage":"HTTP request failed","response":{"statusCode":401,"body":{"status":"error","message":"Authentication credentials not found.

Hi [@Yenma\_H](https://community.hubspot.com/t5/user/viewprofilepage/user-id/222506), I tried to run the script on my end and I had the same authentication issue. Here’s how to troubleshoot : - Make sure you add the API key as a secret on your node ![LMeert_0-1649162308152.png](https://d2qpr2jzcazej7.cloudfront.net/original/2X/1/11414c757e283e4757f6278d910e043508fbced0.png) - Also, you will have to change the name of the variable in the code line 13 : apiKey : process.end.HAPI\_Key And you should be good to go ! If this helped, consider marking this as a solution 🙂 Have a good day, Ludwig ---

Thank you so much! I did end up figuring it out after some trial and error. This was the solution I used. I appreciate your help!
