ember - store.pushPayload - does not belong to this store instance

I have recently updated my ember project code from ember 3.16 to ember 5.12 (and ember-data to 5.3.0)

The following piece of code worked fine in ember 3.16 (without even injecting the store service explicitly).

// =========route.ts============
export default class TopologyViewRoute {
      // == Dependencies ==========================================================
      @service notifier: any
      @service store: any           // The code worked find w/o this line in ember 3.16
      
      constructor () {
        super(...arguments)
        this.rFetch = new RFetch(genericTopologyAdapter, genericTopologySerializer, genericTopologyParser)
      }
      
      @task({restartable: true})
      * _fetchT (): TaskGenerator<object> {
        const topologies = yield this.rFetch.fetch({
            adapterOptions: {
              context: this.contextPayload
            },
            serializerOptions: {
              store: this.store
            }
          })
          return topologies
      }
    }
    
    
    // ===========addon/rfetch.ts===============
    
    async fetch (
        {adapterOptions = {}, serializerOptions = {}} :
        RFetchOptions = {adapterOptions: {}, serializerOptions: {}}
      ): Promise<RFetchResult> {
        const {url, fetchOptions} = this.adapter(adapterOptions)
        const response = await fetch(url, fetchOptions || {})
        const payload = await response.json()
        return {payload, normalized: this.serializer(payload, serializerOptions)}
      }
      
    // ============addon/generic-topo.js  =================
    export function genericTopologySerializer (payload: Document, {store}: {store: Store}) {
      const includedHash = _.keyBy(payload.included, 'id')
    
      const formattedIncluded = payload.included?.reduce((currentIncluded, element) => {
        _.set(element, 'attributes.externalSource', element.meta?.externalSource)
    
        const updatedElement = _getUpdatedAggregateElement({element, includedHash})
    
        return [...currentIncluded, updatedElement]
      }, [])
    
      const includedForStore = formattedIncluded?.filter((object: ResourceIdentifier) => object.type !== 'topologies') || []
      if (includedForStore) store.pushPayload({data: includedForStore})  // store is null if not injected in TopologyViewRoute
    
      return {...payload, included: formattedIncluded}
    }

But after updating ember, I started getting error "can't call pushPayload on undefined", which I resolved by injecting the store service. But since then, I am getting below error

The supplied identifier {"type":"management-session","id":"19dc2cfe-e028-4bfd-a162-a12b5e352d6b","lid":"@lid:management-session-19dc2cfe-e028-4bfd-a162-a12b5e352d6b"} does not belong to this store instance

I am not sure why is it complaining about the store and I am passing and using the same store. Is there any other deprecation that I might be missing?
