you're passing the 'content-length' header from the server action request to the trpc request which causes a content-length mismatch try replacing your headers function in your trpc link for something like this

headers() {
            const h = new Map(headers())

            for (const [key] of h.entries()) {
              if (key === 'content-length' || key === 'content-type') {
                h.delete(key)
              }
            }

            return Object.fromEntries(h.entries());;
          },

headers() {
            const h = new Map(headers())

            for (const [key] of h.entries()) {
              if (key === 'content-length' || key === 'content-type') {
                h.delete(key)
              }
            }

            return Object.fromEntries(h.entries());;
          },
