# GitHub Limitations and Troubleshooting

Learn about the functional limitations of the GitHub connector that affect certain behaviors and outcomes.
The solutions listed below are unique to the GitHub connector.
If your issue applies to other connectors, check [this guide](https://help.salesforce.com/s/articleView?language=en_US&id=data.c360_a_limits_and_guidelines.htm&type=5) for instructions.

The following are limitations or troubleshooting information:

See the [Unstructured Data File Formats and Connectors](https://help.salesforce.com/s/articleView?id=data.c360_a_unstructured_data_connect.htm&type=5) for a list of supported file formats.

## General Data 360 Limitations

Learn about [Data 360's general limitations](https://help.salesforce.com/s/articleView?language=en_US&id=data.c360_a_limits_and_guidelines.htm&type=5) which may create issues for this specific connector.

## A Data Lake Object and a Data Model Object Were Created, But the Search Index and Chunking Failed

When you create a new GitHub connector, you can enable search indexing.

### Issue

Search Index or chunks weren't created.

### Solution

Create or rebuild the search index:

1. From App Launcher, select **Data Cloud**.
2. Do **one** of the following:
3. If you already have a Search index, open the **Search Index** tab, select the Search Index you created, and click **Rebuild** from the dropdown menu on the right.
4. If you need to create a Search index, from the Search Index tab: Click **New > Easy Setup**, and select the corresponding Data Model Object.

## Private Repository Access (404 Errors)

If your GitHub connector passes the connection test and accesses public repositories but returns 404 errors for private
repositories, you may be experiencing a permissions issue with a Fine-grained Personal Access Token (tokens starting with github*pat*).

### Issue

By default, fine-grained tokens may not have access to all repositories.
GitHub intentionally returns a 404 (Not Found) error instead of a 403 (Forbidden) error for repositories the token cannot access to prevent revealing the existence of private repositories.

### Solution

Change your token settings to include the relevant private repositories:

1. Log in to GitHub.com and navigate to **Settings > **Developer settings** > **Personal access tokens** > **Fine-grained tokens\*\*.
2. Select the token you are using for the GitHub connector.
3. Open the settings to edit it.
4. Under the **Repository access section**, ensure you have selected either:
   1. **All repositories (simplest option)**, OR
   2. **Only selected repositories** (and manually add every private repository you need to sync).
5. Under **Repository permissions**, verify that **Contents** is set to **at least** _Read_ access.
