Tag values with Flux query

Fluxlang
1

Hello,
I’m in need of help with a query that has been working fine for months but then suddenly stopped.
I’m running Influx 1.8 with a “influxdb-client-java” connector. Thus I’m limited to Flux as a query language, A query I had working is:

import “influxdata/influxdb/v1”
v1.measurementTagValues(bucket: “mydb/autogen”, measurement: “marketData”, tag: “symbol” )

Data is still there is I query the database with

show tag values from marketData with key=“symbol”

But Flux query returns empty. What could go wrong ? Direction to investigate

Hey! Thanks for attention to the matter.
I did some more research and found that
function “v1.measurementTagValues” is essentially

tagValues(
bucket: bucket,
tag: tag,
predicate: (r) => r._measurement == measurement
)

“start” param is omitted and seems to default to “-30d”, So I have changed to a call

import “influxdata/influxdb/v1”
v1.tagValues(
bucket: “mydb/autogen”,
tag: “symbol”,
predicate: (r) => r._measurement == “marketData”,
start: -10y)

That worked like a charm, looks like “v1.measurementTagValues” isn’t designed for older measurements but seems wrong and unexpected.
Anyways, would you like to get a ticket for this issue still ?
