Switched from btao to Buffer, however encountering a TypeError while trying to push to Vercel

I am currently working on an application in Next.js where I need to encode my image to base64. Initially, I used btao and it worked well until I tried deploying to Vercel, which resulted in an error stating that btao was undefined. After researching a solution, I found that using

Buffer.from(
   icon,
   "binary"
).toString("base64")

should resolve the issue. However, upon redeploying to Vercel, I encountered the following error:

Unhandled error during request: TypeError [ERR_INVALID_ARG_TYPE]: The first argument must be of type string or an instance of Buffer, ArrayBuffer, or Array or an Array-like Object. Received null

Is there anyone else who has faced this problem?

Answer №1

I finally discovered the solution.

It turns out that my SVG file was initially saved as a raw string in the state and when the page loaded, it was being encoded using Buffer.

To resolve this problem, I made sure to encode the SVG string with Buffer at the time of upload and stored the encoded string in the state so that it wouldn't need to be encoded every time the page loads.
