InfluxDB users encountered several issues in the last week, including mixing aggregate functions with non-aggregate queries, which resulted in an error due to InfluxDB's syntax limitations. Additionally, users tried to update Continuous Queries after creation but found that this is not currently supported by InfluxDB. Furthermore, users experienced errors when inserting data into InfluxDB due to incorrect timestamp formatting, which was caused by a syntax error resulting from whitespace sensitivity in the line protocol. To resolve these issues, users need to adjust their queries and data insertion syntax according to InfluxDB's specifications, such as separating fields with commas instead of spaces.
