Hi,

I am using Telegraf to capture data of a local ip address (http:192.168.X.Y/getvar.csv) / csv file and storing it in influxdb. This is my config file:

```auto
# Configuration for telegraf agent
[agent]
  ## Default data collection interval for all inputs
  interval = "5s"
  round_interval = true

  ## Telegraf will send metrics to outputs in batches of at most
  ## metric_batch_size metrics.
  ## This controls the size of writes that Telegraf sends to output plugins.
  metric_batch_size = 1000

  ## Maximum number of unwritten metrics per output. Increasing this value
  ## allows for longer periods of output downtime without dropping metrics at the
  ## cost of higher maximum memory usage.
  metric_buffer_limit = 10000

  ## Collection jitter is used to jitter the collection by a random amount.
  ## Each plugin will sleep for a random time within jitter before collecting.
  ## This can be used to avoid many plugins querying things like sysfs at the
  ## same time, which can have a measurable effect on the system.
  collection_jitter = "0s"

  ## Default flushing interval for all outputs. Maximum flush_interval will be
  ## flush_interval + flush_jitter
  flush_interval = "10s"
  ## Jitter the flush interval by a random amount. This is primarily to avoid
  ## large write spikes for users running a large number of telegraf instances.
  ## ie, a jitter of 5s and interval 10s means flushes will happen every 10-15s
  flush_jitter = "0s"

  ## By default or when set to "0s", precision will be set to the same
  ## timestamp order as the collection interval, with the maximum being 1s.
  ## ie, when interval = "10s", precision will be "1s"
  ## when interval = "250ms", precision will be "1ms"
  ## Precision will NOT be used for service inputs. It is up to each individual
  ## service input to set the timestamp at the appropriate precision.
  ## Valid time units are "ns", "us" (or "µs"), "ms", "s".
  precision = ""

  ## Log at debug level.
  # debug = false
  ## Log only error level messages.
  # quiet = false

  ## Log target controls the destination for logs and can be one of "file",
  ## "stderr" or, on Windows, "eventlog". When set to "file", the output file
  ## is determined by the "logfile" setting.
  # logtarget = "file"

  ## Name of the file to be logged to when using the "file" logtarget. If set to
  ## the empty string then logs are written to stderr.
  # logfile = ""

  ## The logfile will be rotated after the time interval specified. When set
  ## to 0 no time based rotation is performed. Logs are rotated only when
  ## written to, if there is no log activity rotation may be delayed.
  # logfile_rotation_interval = "0d"

  ## The logfile will be rotated when it becomes larger than the specified
  ## size. When set to 0 no size based rotation is performed.
  # logfile_rotation_max_size = "0MB"

  ## Maximum number of rotated archives to keep, any older logs are deleted.
  ## If set to -1, no archives are removed.
  # logfile_rotation_max_archives = 5

  ## Pick a timezone to use when logging or type 'local' for local time.
  ## Example: America/Chicago
  # log_with_timezone = ""

  ## Override default hostname, if empty use os.Hostname()
  hostname = ""
  ## If set to true, do no set the "host" tag in the telegraf agent.
  omit_hostname = false
[[outputs.influxdb_v2]]

  urls = ["http://192.168.X.X:8086"]

  ## Token for authentication.
  token = "XXX"

  ## Organization is the name of the organization you wish to write to; must exist.
  organization = "XXX Inc"

  ## Destination bucket to write into.
  bucket = "XXX_STATS"

[[inputs.http]]
  urls = ["http://192.168.X.Y/getvar.csv"]
  data_format = "csv"
  csv_header_row_count = 1
  csv_measurement_column = ["name"]
  csv_tag_columns = ["id"]
  csv_column_types = ["string","float","string","string","string","string"]

[[processors.converter]]
  [processors.converter.fields]
    float = ["val"]

```

I get this error message in my telegraf docker logs:

```auto
022-07-24T15:28:42Z E! [inputs.http] Error in plugin: [url=http://192.168.X.Y/getvar.csv]: instantiating parser failed: line 95: (csv.Parser.MeasurementColumn) cannot unmarshal TOML array into string (need slice)

```

Does anybody know what is wrong with my config file?

Many thanks!

_csv\_measurement\_column_ is not an array, write

```auto
csv_measurement_column = "name"

```
