Based on the description of the error you're encountering, it seems the issue primarily revolves around the expiration and renewal of access tokens used for authentication with your application's REST API. Given the intermittent nature of the issue, a likely cause is the token refresh mechanism not functioning as expected, or the application not handling expired tokens correctly, causing failed attempts at data reconciliation.
To address these issues, it's important to implement a robust mechanism for managing authentication tokens, including their renewal before expiration and handling errors related to token expiration effectively. Below is an example JSON configuration for a REST connection that includes fields for error handling and token management, adapted from the REST Connector Guide. This configuration outlines how to specify error handling for expired tokens and the retry mechanism, ensuring the connector attempts to refresh the token or reauthenticate as needed.
{
"ConnectionName": "YourApplicationConnection",
"ConnectionDescription": "Connection for Application XYZ",
"ConnectionType": "REST",
"authtype": "OAuth",
"authError": [
"InvalidAuthenticationToken",
"AuthenticationFailed",
"Access token expired"
],
"errorPath": "error_description",
"retryFailureStatusCode": [401, 403],
"maxRefreshTryCount": 3,
"ConnectionJSON": {
"authentications": {
"authType": "OAuth",
"tokenURL": "https://yourapplication.com/oauth/token",
"clientId": "YourClientId",
"clientSecret": "YourClientSecret",
"scope": "requiredScope",
"grantType": "refresh_token",
"refreshToken": "YourRefreshToken",
"accessTokenPath": "access_token",
"expiryPath": "expires_in",
"tokenType": "Bearer",
"httpMethod": "POST"
}
}
}
Key Components:
- authError: Lists the possible error messages or codes returned by the API that indicate an authentication or token issue. When the connector encounters these errors, it knows to attempt a re-authentication or token refresh.
- errorPath: Specifies the JSON path in the API response where the connector can find error messages or codes. This path helps the connector identify whether an encountered error is related to authentication.
- retryFailureStatusCode: Includes HTTP status codes that should trigger a retry, typically because they indicate a token or authentication issue.
- maxRefreshTryCount: Defines how many times the connector should attempt to refresh the token or reauthenticate after encountering an authentication error before giving up.
- ConnectionJSON: This section should be tailored to the specifics of your application's authentication mechanism. For OAuth, it includes token endpoint information, client credentials, and paths for retrieving the access token and its expiration time from the authentication response.
Ensure your application's backend or the REST API itself robustly handles token expiration scenarios, such as attempting to refresh the token before it expires and providing clear error responses when the token is invalid or expired. Properly implementing such mechanisms can prevent issues like the one you've described and ensure more reliable connectivity and data processing.
