Zod - instanceof z.ZodError

    try {
      coursePOST.body.parse(requestBody);
    } catch (error) {
      if (error instanceof z.ZodError) {
        setError(error.issues[0].message);
      }
      return;
    }

    try {
      coursePOST.body.parse(requestBody);
    } catch (error) {
      if (error instanceof z.ZodError) {
        setError(error.issues[0].message);
      }
      return;
    }

    try {
      coursePOST.body.parse(requestBody);
    } catch (error) {
      if (error instanceof z.ZodError) {
        setError(error.issues[0].message);
      }
      return;
    }

    try {
      coursePOST.body.parse(requestBody);
    } catch (error) {
      if (error instanceof z.ZodError) {
        setError(error.issues[0].message);
      }
      return;
    }

For some reason, the error is not being recognized as an instanceof Zod and I have no idea why. Anything wrong I am not seeing?

Maybe try extracting the coursePost to it's own schema?

This is from the docs:

try {
  person.parse({
    names: ["Dave", 12], // 12 is not a string
    address: {
      line1: "123 Maple Ave",
      zipCode: 123, // zip code isn't 5 digits
      extra: "other stuff", // unrecognized key
    },
  });
} catch (err) {
  if (err instanceof z.ZodError) {
    console.log(err.issues);
  }
}

try {
  person.parse({
    names: ["Dave", 12], // 12 is not a string
    address: {
      line1: "123 Maple Ave",
      zipCode: 123, // zip code isn't 5 digits
      extra: "other stuff", // unrecognized key
    },
  });
} catch (err) {
  if (err instanceof z.ZodError) {
    console.log(err.issues);
  }
}

Your code seems right, have you tried passing random things to be parsed?

I guess it’s a known bug if importing a zod object @ygor perez
