Python Client append fields error

[ayaghini]

I am trying to write to influxDB, using python the following information:

`point = (
Point("myMeasuremnt")
.tag("device", "myDevice)
.field("data", [a flatten() array of 270 x,y,z points)
.time(datetime.utcnow(), WritePrecision.NS)
)

self.write_api.write(bucket=bucket, record=point)`

and getting following error:
File "C:\Python37\lib\site-packages\influxdb_client\client\write\point.py", line 168, in _append_fields
raise ValueError()
builtins.ValueError:

the extended version of the error:

raise ValueError()

Apologies if this is not relevant, but I did google and could not find any answer to this issues.

Thanks for your help.

Hi @ayaghini,

the error is caused by unsupported type of field that you want to append to Point.

This expression: .field("data", [a flatten() array of 270 x,y,z points) seems to be invalid.
