s3 type error

Not great at typescript so I'm not sure why this is throwing a type error.

export const r2 =
  globalForR2.r2 ||
  new S3Client({
    region: "auto",
    endpoint: process.env.AWS_ENDPOINT,
    credentials: {
      accessKeyId: process.env.AWS_ACCESS_KEY_ID,
      secretAccessKey: process.env.S3_SECRET_ACCESS_KEY,
    },
  });

export const r2 =
  globalForR2.r2 ||
  new S3Client({
    region: "auto",
    endpoint: process.env.AWS_ENDPOINT,
    credentials: {
      accessKeyId: process.env.AWS_ACCESS_KEY_ID,
      secretAccessKey: process.env.S3_SECRET_ACCESS_KEY,
    },
  });

Env variables can be undefined, so Typescript's type for an env var is string | undefined, if you have a type string you cannot assign it string | undefined because string is not undefined, if you want to tell TS that a variable/property is NOT undefined, you can append ! at the end, so in this case you could do this and should be fine:

export const r2 =
  globalForR2.r2 ||
  new S3Client({
    region: "auto",
    endpoint: process.env.AWS_ENDPOINT!,
    credentials: {
      accessKeyId: process.env.AWS_ACCESS_KEY_ID!,
      secretAccessKey: process.env.S3_SECRET_ACCESS_KEY!,
    },
  });

export const r2 =
  globalForR2.r2 ||
  new S3Client({
    region: "auto",
    endpoint: process.env.AWS_ENDPOINT!,
    credentials: {
      accessKeyId: process.env.AWS_ACCESS_KEY_ID!,
      secretAccessKey: process.env.S3_SECRET_ACCESS_KEY!,
    },
  });
