I was experiencing the same issue on our org. I reset the ELT script back to a default version without builder input, ran the Data flow Manually, it was successful. I then added some extra objects and various fields to the ELT Data flow via the dataset builder and the flow was successful again.
Below is my "default" version of a ELT JSON, This should work with all orgs:
{
"100": {
"action": "sfdcDigest",
"parameters": {
"object": "Account",
"fields": [
{
"name": "Description"
},
{
"name": "Fax"
},
{
"name": "Id"
},
{
"name": "Name"
},
{
"name": "Phone"
},
{
"name": "AccountSource"
},
{
"name": "Type"
},
{
"name": "AnnualRevenue"
},
{
"name": "BillingCity"
},
{
"name": "BillingCountry"
},
{
"name": "BillingLatitude"
},
{
"name": "BillingLongitude"
},
{
"name": "BillingState"
},
{
"name": "BillingStreet"
},
{
"name": "BillingPostalCode"
},
{
"name": "CreatedDate"
},
{
"name": "Jigsaw"
},
{
"name": "IsDeleted"
},
{
"name": "NumberOfEmployees"
},
{

{

{

}
},
"101": {
"action": "sfdcDigest",
"parameters": {
"object": "Account",
"fields": [
{

{

}
},
"102": {
