Error getting access token - JWT signature

[aliciac16425319]

This is my first time posting, so please let me know if there's anything I need to change about this question. I've searched the forums with any key words I could think of, as well as Google, and haven't been able to find anything like this.

I'm trying to update a script that accesses the adobe api, and is currently working in production. To update it, I need to get it working on my local computer, and right now, when I attempt to connect to the AdobeIO API, I am given the error:

Error getting access token: {"error_description":"Could not match JWT signature to any of the bindings","error":"invalid_token"}

Does anyone know what this could mean? The token doesn't expire until next year, and the error section in the adobe documentation doesn't mention this specific error. As far as I can tell, the private key is in the right format, so I don't think that's the issue either.

Any help would be greatly appreciated.

Hi Alicia,

I think you have the wrong forums as this section of the forums is for Adobe Business Catalyst.

I think if you click Product downdown menu at the top of these forums, you can choose the adobe product you're after.

Thank you for your response, Stephen! It turns out the certificate had expired and I didn't have the right private key anymore. Have a great day!
