[bz888]

Prerequisites

• When running a project with multiple datasources

Description

subql/packages/node-core/src/indexer/fetch.service.ts

Line 233 in c3c5080

const handlers = [...this.projectService.getAllDataSources().map((ds) => ds.mapping.handlers)].flat();

Should be getting current and future datasources instead of all ds

getModulos implementation is also using getAllDataSources. getModulos should be updated to take in the datasources that are used with this change

This was fixed in #2225 and regression restored #2320
