How to find the "Local Identifier" to execute AFM function using gooddata-js - gooddata

Question

I'm using gooddata-js in my project and I'm trying to use the function execution.executeAfm, but appears error about "Local identifier no found in AFM".
I followed the documentation about AFM and Result Specification, but I don't know where I find the "Local identifier" to put into itemIdentifiers. I tried put ['measureGroup'] but didn't work!
execution: {
afm: {
measures: [
// Type: IMeasure
{
localIdentifier: '740953a40a01490c8aaeba66a21cac53',
// Type: MeasureDefinition
definition: {
measure: {
// Type: ObjQualifier
item: {
uri: '/gdc/md/PROJECT_ID/obj/245828'
},
filters: [
// Type: IAbsoluteDateFilter
{
relativeDateFilter: {
dataSet: {
uri: '/gdc/md/PROJECT_ID/obj/3603'
},
from : 0,
granularity : 'GDC.time.month',
to : 0
}
},
],
computeRatio: false
}
},
}
]
},
resultSpec:
{
dimensions: [
{
itemIdentifiers: ['gdc.visualization.table']
}
]
}
}
I expect result of AFM function but show the error below!
error: {errorClass: "com.gooddata.webapp.service.executeafm.exception.LocalIdentifierNotFoundException",…}
component: "Webapp"
errorClass: "com.gooddata.webapp.service.executeafm.exception.LocalIdentifierNotFoundException"

0: "gdc.visualization.table"
1: "AttributeItem"

You are looking for a documentation of resultSpec available here:
https://sdk.gooddata.com/gooddata-ui/docs/result_specification.html
From your code snippet, I can only guess that a valid resultSpec could look something like this:
{
"dimensions": [
{
"itemIdentifiers": [
"measureGroup"
]
},
{
"itemIdentifiers": []
}
],
"sorts": []
}
