Hello to you who is currently reading this right now,

i've been faced with an issue i've been trying to resolve for the past few days now but with no success. This is part of my diplom thesis ba the way.

The error i've been encountering can be seen in the image above.

I have tried importing the library through platform.io and manually in an attempt to resolve the issue but to no avail.

Is there something that i am missing here?

A reply would be really helpful,
Thank you!
