AJV v8.17.1 has been working for validations in our project for a while, but we never used it for any arrays. When used for this object:

{"name":"a","codes":["A01"]}

it's throwing:

strict mode: unknown keyword: \"elements\"

Here is the validation code:

export type TempDetails = {
  name: string;
  codes: string[];
};

export type JTDTempDetailsCreateRequestSchema = JTDSchemaType<TempDetails>;

export const jtdTempDetailsCreateRequestSchema: JTDTempDetailsCreateRequestSchema = {
  properties: {
    name: { type: 'string' },
    codes: { elements: { type: 'string' }, nullable: false },
  },
};

const ajv = new Ajv();

const validate = ajvpile<TempDetails>(jtdTempDetailsCreateRequestSchema);

if (!validate(untypedClass)) 
    throw new BadRequest(`Invalid Request: ${JSON.stringify(validate.errors)}`);

update your code to this. You didn't define the code array correctly

properties: {
    name: { type: 'string' },
    codes: { type: 'array', 
             items: { 
               type: 'object': { 
               properties: { 
                 elements: { type: 'string', nullable: false }}}}},
  },

EDIT: your example doesn't match the schema you have

{"name":"a","codes":["A01"]}

This would be equivalent to this

properties: {
    name: { type: 'string' },
    codes: { type: 'array', 
             items: { type: 'string', nullable: false }},
  },
