Upsert External ID Issue dml

[DanielAD84]

I'm getting the issue below with upserting a External ID. Thoughts Thanks!

This
NOT_FOUND: Provided external ID field does not exist or is not accessible:

Code below

dml := &dml{
sobject: "Facebook_7FF__c",
fields: map[string]interface{}{
"Ad_Spent_Cents__c": "$10000",
"Clicks__c": "200",
"Entered_Date_Time__c": "12/4/2019, 5:10:20 PM",
"LMS_ID__c": "2324",
"LMS_Record_ID__c": "e4f5591f-ca42-4eb5-bd4b-3d6a1d1b2602",
"Leads__c": "5",
"Period_End_Date__c": "11/27/2019",
"Period_Start_Date__c": "11/27/2019",
"Sales_Cents__c": "$2000",
"Scheduled_ss__c": "2",
"Person_Account__c": "a293i0000009ErBAAU",
"clients__c": "1",
"ss__c": "1",
},
}
dml.id = "a293i0000009ErBAAU"
dml.externalField = "75bc21b7-201c-4a90-b716-506785a0c2a0"

Field is setup as Unique and External

So for the upsert to work with an external field, you need to provide the external field name and the value
Here is the example from the documentation

type dml struct {
sobject string
fields map[string]interface{}
id string
externalField string
}

func (d *dml) SObject() string {
return d.sobject
}
func (d *dml) Fields() map[string]interface{} {
return d.fields
}
func (d *dml) ID() string {
return d.id
}
func (d *dml) ExternalField() string {
return d.externalField
}

sobjResources := sobject.NewResources(session)

dml := &dml{
sobject: "Account",
}
dml.id = "AccExID345"
dml.externalField = "MyUID__c"
dml.fields["Name"] = "Upsert Update"

upsertValue, err := sobjResources.Upsert(dml)

if err != nil {
fmt.Printf("Upsert Error %s\n", err.Error())
return
}

fmt.Println("Account Upsert")
fmt.Println("-------------------")
fmt.Printf("%+v\n", upsertValue)

so from your example, the external field is the field name and the id would be the 75...2a0
