Troubleshoot issues writing data
Learn how to avoid unexpected results and recover from errors when writing to InfluxDB Cloud Dedicated.
In InfluxDB Cloud Dedicated, writes are synchronous.
After InfluxDB validates the request and ingests the data, it sends a success response (HTTP
204 status code) as an acknowledgement that the data is written and queryable.
To ensure that InfluxDB handles writes in the order you request them, wait for the acknowledgement before you send the next request.
If InfluxDB successfully writes all the request data to the database, it returns success (HTTP
204 status code).
The first rejected point in a batch causes InfluxDB to reject the entire batch and respond with an HTTP error status.
Review HTTP status codes
InfluxDB uses conventional HTTP status codes to indicate the success or failure of a request.
message property of the response body may contain additional details about the error.
Write requests return the following status codes:
|HTTP response code||Message||Description|
|If InfluxDB ingested the data|
|If data is malformed|
|If the |
|requested resource type (for example, “organization” or “database”), and resource name||If a requested resource (for example, organization or database) wasn’t found|
|Default status for an error|
|If the server is temporarily unavailable to accept writes. The |
If your data did not write to the database, see how to troubleshoot rejected points.
If you notice data is missing in your database, do the following:
- Check the
messageproperty in the response body for details about the error.
- If the
messagedescribes a field error, troubleshoot rejected points.
- Verify all lines contain valid syntax (line protocol).
- Verify the timestamps in your data match the precision parameter in your request.
- Minimize payload size and network errors by optimizing writes.
Troubleshoot rejected points
InfluxDB rejects points for the following reasons:
- The batch contains another point with the same series, but one of the fields has a different value type.
- The bucket contains another point with the same series, but one of the fields has a different value type.
