# OpsHub-012000

### Description

When you encounter OpsHub-012000, then the following message appears:

OpsHub-012000: Processing blocked - Processing is already in progress or has failed for the corresponding target entity; this target entity has to be processed first, then you may require retrying failure for this entity `<entity_id>`

### Cause

The reason for this error is presence of a failed event on the same entity from the integration.\ <code class="expression">space.vars.OIM</code> blocking this event for data consistency reasons. For example if integration from system A to system B had started event synchronization and done a partial update in system B and then an event failure came, in such cases if <code class="expression">space.vars.OIM</code> allows event synchronization for that entity from system B to system A, then it can result into data inconsistency. To prevent data inconsistency <code class="expression">space.vars.OIM</code> block such event.

### Solution

1. First resolve the failures on the other way integration for this entity.
   * To find the integration failures for this entity, you will need entity id from other system that is synchronized with this entity id. To find the entity id, you can use [Integration\_Sync\_Report](/v7.237/help-center-index/troubleshooting-index/integration-sync-report.md) feature.
   * Once you found other system entity id, navigate to other way integration failure queue and search that entity id. You can use 'Entity Id' filter for this. For more information on how to apply filter on event failure, refer [Filtering failures](/v7.237/help-center-index/troubleshooting-index/manage-integration-failures.md#filtering-failures)
   * Understand the error and resolve this failures.
2. Now go to integration for which this error came, retry the failure by clicking 'Retry All With Dependents' failure option. For more information on how to retry failed event, refer [Action-on-failures](/v7.237/help-center-index/troubleshooting-index/manage-integration-failures.md#action-on-failures)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.opshub.com/v7.237/help-center-index/troubleshooting-index/errors-index/common-error-solutions/opshub-012000.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
