'arcgis Failed to load layer: Cannot read properties of undefined (reading 'bind')
I'm trying to query a public ArcGIS server using a some a node script in Typescript but I'm getting the error:
[esri.layers.FeatureLayer] #load() Failed to load layer (title: 'Subway tcl stations center wgs84', id: '180b472baf2-layer-0') {
error: TypeError: Cannot read properties of undefined (reading 'bind')

}
The relevant code is:
package.json
{
"name": "arcgis-query",
"version": "0.0.0",
"main": "./src/main.ts",
"type": "module",
"license": "GPL",
"private": true,
"dependencies": {
"@arcgis/core": "^4.23.7",
"typescript": "^4.6.3"
},
"scripts": {
"build": "tsc",
"start": "node ./out/main.js"
}
}
tsconfig.json
{
"compilerOptions": {
"target": "ES2020",
"module": "ES2020",
"rootDir": "src",
"moduleResolution": "node",
"outDir": "./out",
"esModuleInterop": true,
"forceConsistentCasingInFileNames": true,
"strict": true,
"noImplicitAny": true,
"skipLibCheck": true
}
}
src/main.ts
import FeatureLayer from '@arcgis/core/layers/FeatureLayer.js'
import Query from '@arcgis/core/rest/support/Query.js'
import SpatialReference from '@arcgis/core/geometry/SpatialReference.js'
const main = async (): Promise<void> => {
const url: string =
'https://services.arcgis.com/V6ZHFr6zdgNZuVG0/ArcGIS/rest/services/subway_tcl_stations_center_wgs84/FeatureServer/0'
const featureLayer = new FeatureLayer({ url })
const query = new Query({
outSpatialReference: SpatialReference.WGS84,
})
const featureSet = await featureLayer.queryFeatures(query)
console.log('Feature Set', featureSet)
}
main()
Run with yarn install && yarn build && yarn start
and I get the error above.
If I insert await featureLayer.load()
before querying I get the same error.
The "undefined 'bind'" message implies to me that it's trying display the feature layer to somewhere, but I haven't told it where yet, because I don't want to display it at all. This is strictly a console application.
update: Typescript isn't the issue. It seems to be running arcgis code in node that's the problem. If I translate src/main.ts
to src/main.js
like so:
import FeatureLayer from '@arcgis/core/layers/FeatureLayer.js'
import Query from '@arcgis/core/rest/support/Query.js'
import SpatialReference from '@arcgis/core/geometry/SpatialReference.js'
const main = () => {
const url =
'https://services.arcgis.com/V6ZHFr6zdgNZuVG0/ArcGIS/rest/services/subway_tcl_stations_center_wgs84/FeatureServer/0'
const featureLayer = new FeatureLayer({ url })
const query = new Query({
outSpatialReference: SpatialReference.WGS84,
})
featureLayer.queryFeatures(query).then(featureSet => {
console.log('Feature Set', featureSet)
})
}
main()
and run with node src/main.js
I get the same error.

It looks like the library I was using is strictly for in-browser usage. I should've been using @esri/arcgis-rest-feature-service
instead.
package.json
{
"name": "arcgis-query",
"version": "0.0.0",
"main": "./src/main.ts",
"type": "module",
"license": "GPL",
"private": true,
"dependencies": {
"@esri/arcgis-rest-feature-service": "^4.0.3",
"@esri/arcgis-rest-portal": "^4.0.3",
"@esri/arcgis-rest-request": "^4.0.3",
"typescript": "^4.6.3"
},
"scripts": {
"build": "tsc",
"start": "node ./out/main.js"
}
}
src/main.ts
import * as arcgisRest from "@esri/arcgis-rest-request"
import * as arcgisRestFeatureService from "@esri/arcgis-rest-feature-service"
const main = async (): Promise<void> => {
const url: string =
'https://services.arcgis.com/V6ZHFr6zdgNZuVG0/ArcGIS/rest/services/subway_tcl_stations_center_wgs84/FeatureServer/0'
const featureSet = await arcgisRestFeatureService.queryFeatures({
url
})
console.log('Feature Set', featureSet)
}
main()

Just to prove that the code should work. I use another service that has less features in order to work easy.
