cds-bug-3's Introduction

Problem description

Requirement

As part of a longer running service to execute a set of functionalities, I would like to update a processing status in a database table.

Problem description

I don't want all updates to be committed at the end of the service execution, but I need incremental commits to the database at the time the status update is triggered. I believe that requires an indepdendent transaction bracket. An example of that is implemented in the transaction handler: synch.js

The solution seems to hang (maybe a db lock?) once the update to the status runs.

Replication of problem

Clone this repository
Run npm install
Run cds watch
Open ./test/synch.http to call the action

the result you should see in the terminal is something like this

[cds] - POST /synch/startSynch 
Run Status [
  {
    ID: '002f90b4-97c1-40c6-881c-484cff305692',
    createdAt: '2023-06-08T15:59:21.838Z',
    createdBy: 'anonymous',
    modifiedAt: '2023-06-08T15:59:21.838Z',
    modifiedBy: 'anonymous',
    entityName: 'User',
    srcDestinationName: 'sf-inno-api',
    sfCompanyId: null,
    fieldsToFilter: null,
    synchProgress: 'Started'
  }
]

problem is that the line console.log('sync') is never reached.
