## Short answer

SSS_MISSING_REQD_ARGUMENT means a NetSuite API call, most often record.create(), record.load(), or search.create(), was called without a parameter that method requires, such as type or id. Fix it by checking the object literal you passed against the current SuiteScript 2.x API signature and confirming no required key is undefined at runtime.

## Alternate Queries

- NetSuite missing required argument suitescript

## Applies To

NetSuite SuiteScript 2.0 and 2.1, N/record, N/search, N/format modules

## Steps

### How to fix SSS_MISSING_REQD_ARGUMENT

**Items:**

Read the error's stack context in the Script Execution Log to identify the exact API call and line number.

Compare your call's parameter object against the current SuiteScript 2.x API reference for that method; module signatures do change slightly between API versions.

Most commonly, check record.create({type, isDynamic}) for a missing or undefined type, or record.load({type, id}) for a missing id.

Add a defensive check before the call: if (!recordId) { log.error('Missing id', context); return; } so a null upstream value fails loudly with context instead of a generic governance error.

For search.create(), confirm both type and either filters or columns are present; an empty columns array combined with a missing type is a frequent trigger.

If the value is coming from a parameter passed into a Scheduled Script or Map/Reduce via the deployment's script parameters, verify the parameter is actually populated on that specific deployment record, not just a different deployment.

For RESTlet or Suitelet requests, log the raw incoming request body before parsing, since a missing key in the JSON payload from the caller propagates directly into a missing required argument downstream.

## Sections

### Where this typically originates

**Body:**

SSS_MISSING_REQD_ARGUMENT is thrown by the SuiteScript runtime itself, before your business logic even executes, whenever a required key in an API call's options object is undefined or absent. Unlike a JavaScript TypeError, it is NetSuite's own parameter validation, so the stack trace points at the governance layer rather than your function.

The two most common offenders are record.create() without a type, and record.load() without an id. Both usually happen because the value being passed in was itself undefined upstream, for example a search result column that returned null because the joined field was empty on that particular record.

### Script parameters and deployment context

**Body:**

When a Scheduled Script or Map/Reduce script reads a custom script parameter with runtime.getCurrentScript().getParameter(), a missing value there is often not a script bug but a deployment configuration gap: the parameter was set on one deployment record but the script is actually executing under a different deployment that never had the value filled in.

Always confirm which deployment triggered the failing execution (visible in the Scheduled Script Status list or the execution log header) and open that specific deployment record's parameters tab, not just the script record's default parameters.

### Defensive coding pattern

**Body:**

Wrap every API call that takes a required id or type with an explicit guard clause and a descriptive log entry before the call executes. This turns an opaque SSS_MISSING_REQD_ARGUMENT into a clear, business-meaningful log line that tells you which upstream record or search produced the gap.

For integrations receiving external JSON payloads, validate the payload schema at the top of the RESTlet function rather than letting missing keys surface deep inside record API calls several functions later.

**Code:**

function safeLoad(type, id) {
  if (!id) {
    log.error({ title: 'Missing id for load', details: type });
    return null;
  }
  return record.load({ type: type, id: id });
}

## Pitfalls

- Passing a search column value straight into record.load({id: value}) without checking it is not null when the joined field is empty on some records.
- Confusing script-record-level default parameters with deployment-specific parameter overrides.
- Upgrading a script from SuiteScript 2.0 to 2.1 without checking for minor required-argument differences in newer API methods.
- Not validating incoming RESTlet or Suitelet JSON payloads before using their fields as API call arguments.
- Assuming a variable is populated because it was set earlier in the function, when an early return or conditional branch actually skipped that assignment.

## Ai Angle

ERPray can walk a failing execution log line by line against your actual script source and deployment parameter records, pointing to the specific missing key and the deployment where the parameter was never populated, rather than you manually opening each deployment record to compare parameter tabs. For integration payloads, it can also flag which field the external system is sending as null or omitted, closing the loop faster than tracing through RESTlet logs by hand.

## Faq

### Is SSS_MISSING_REQD_ARGUMENT the same as a JavaScript undefined error?

**Answer:** No. It is a NetSuite API-level validation error thrown when a required key in a record, search, or format module call is missing or undefined, distinct from a plain JavaScript TypeError, and it always originates from an N/record, N/search, or similar module call.

### Why does record.load fail only for some records?

**Answer:** Usually because the id passed to load() was derived from a search or lookup where the join returned null for those specific records, so the id argument was undefined only in those cases, not a static script bug.

### Can script deployment audience or parameter settings cause this?

**Answer:** Yes. If a Scheduled Script relies on a script parameter that is only populated on one deployment record and a different deployment runs without that value, the parameter read returns null and the next API call throws this error.

### Does this error appear in SuiteScript 1.0?

**Answer:** It is far less common in 1.0 because many nlapiXxx functions default missing arguments rather than throwing, but it can still surface in newer N/ modules used alongside legacy 1.0 code in hybrid scripts.
