I have built a dynamic application that uses the Spotify API, the code should be correct as I have checked it with the example solution. When Running my app, I get the following -
First, it looks like your code is referencing a local Windows file directory. This will not work on Render, as it is a completely different environment that runs on Linux. Ensure your code never references a folder or file within the local file system. Instead, use relative paths from the root directory of the project so when you check the code into the repository and it gets deployed on Render, the code will know where to find what it’s looking for.
Another thing to look out for is ensuring all references to folders/files match the exact casing and spelling, as Linux is case sensitive.
