Writing to the database fails silently when writing tuple with no Exception raised and no effect on the database

[lukas-ba-github]

I spent a bit of time wondering why influxdb does not contain my data or why there is no error raised by influxdb-client-python so please consider this bug report.

Steps to reproduce:

import datetime
from influxdb_client import InfluxDBClient, Point, WritePrecision
from influxdb_client.client.write_api import SYNCHRONOUS

dT = datetime.datetime.utcnow()

org = "testOrg"
url = "http://localhost:8086"
token = '-'
bucket = "testBucket"

p = (
    Point("testM")
    .time(dT, write_precision=WritePrecision.S)
    .tag("testT", "abc")
    .field("testF", 1)
)
client = InfluxDBClient(url=url, token=token, org=org)
write_api = client.write_api(write_options=SYNCHRONOUS)
# fails silently, no error raised even if the database does not exist
record = (p, )
write_api.write(bucket, org, record)

# works
#record = [p, ]
#write_api.write(bucket, org, record)

Expected behavior:
Option A:

• a point is inserted into the database
• Tuples and other iterables are accepted instead of Lists to be more pythonic

Option B:

• only Lists are accepted
• a ValueError is raised for Tuples

Actual behavior:
Nothing happens

Specifications:

• Client Version: influxdb-client 1.10.0
• InfluxDB Version: influxdb 1.8.2-1
• Platform: Linux, Arch Linux

Hi @lukas-ba-github,

thanks for using our client.

It is a nice catch. The option A seems to be a better solution so we will fix it as you suggested.

Hi @lukas-ba-github,

The issue is fixed in 1.11.0 milestone.

If you would like to use a dev version then install client via:

pip install git+https://github.com/influxdata/influxdb-client-python.git@master
