InfluxDB ERR: invalid privilege

The specified privilege is not valid or not supported.

Understanding InfluxDB

InfluxDB is a time-series database designed to handle high write and query loads. It is optimized for fast, high-availability storage and retrieval of time series data in fields such as operations monitoring, application metrics, IoT sensor data, and real-time analytics.

Identifying the Symptom: ERR: invalid privilege

When working with InfluxDB, you might encounter the error message ERR: invalid privilege. This error typically appears when attempting to assign a privilege to a user or role that InfluxDB does not recognize or support.

Understanding the Issue

The error ERR: invalid privilege occurs when the privilege specified in a command is not valid. InfluxDB supports specific privileges such as READ, WRITE, and ALL. Any deviation from these supported privileges will result in this error.

Common Causes

  • Typographical errors in the privilege name.
  • Using unsupported privilege types.
  • Misunderstanding of privilege levels.

Steps to Fix the Issue

To resolve the ERR: invalid privilege error, follow these steps:

Step 1: Verify the Privilege

Ensure that the privilege you are trying to assign is one of the supported types. The supported privileges in InfluxDB are:

  • READ: Allows reading data from the database.
  • WRITE: Allows writing data to the database.
  • ALL: Grants both read and write permissions.

Step 2: Correct the Command

Review the command you are using to assign privileges. Ensure that the privilege is correctly spelled and is one of the supported types. For example:

GRANT READ ON my_database TO my_user;

Step 3: Check Documentation

If you are unsure about the privileges, refer to the official InfluxDB Authorization and Authentication documentation for detailed information on supported privileges.

Step 4: Test the Command

After correcting the command, execute it again to ensure that the error is resolved. If the error persists, double-check the syntax and the user or role names involved.

Conclusion

By following these steps, you should be able to resolve the ERR: invalid privilege error in InfluxDB. Always ensure that you are using the correct and supported privileges to avoid such issues. For more information, you can visit the InfluxDB Documentation.
