Hey Ppl,I am facing following issue on trailhead when i am trying to check challenge after completion of process builder module,Challenge Not yet complete... here's what's wrong: There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Insert failed. First exception on row 0; first error: FIELD_CUSTOM_VALIDATION_EXCEPTION, AnnualRevenue is required: [AnnualRevenue]please helpThanking you
It look like you created "AnnualRevenue" field as required field.Please deactivate the Validation rule (if your created on same field) or remove the required field checkbox.And try again
