Prometheus can't read "cursor"

I'm in Prometheus Remotewrite and remotewrite are correctly configured in yaml, and I also saw Prometheus write data to informdb using show measurements in informdb. This does not seem to be a problem, but I manually create a table such as http_ reqeust_total and constantly customize some data into it. Then I query http_reqesut_total through Prometheus graph, but I can't find it.
And when i query on prometheus, I saw influxdb logs:
ts=2022-08-17T08:12:37.586827Z lvl=info msg="Prometheus can't read cursor" log_id=0cLRYF6l000 service=httpd cursor_type=int64 series="[{__name__ traefik_reqesut_total} {code 200}]"
[httpd] 172.30.24.208 - - [17/Aug/2022:08:12:37 +0000] "POST /api/v1/prom/read?db=grafana&rp=autogen HTTP/1.1 " 200 4 "-" "Prometheus/2.36.2" 5b1fa5a6-1e04-11ed-9f5f-066c3e672749 1299
what is the problem?

Start by reproducing the Prometheus query against the manually created measurement and inspect the InfluxDB /api/v1/prom/read entry point, using the reported “Prometheus can't read cursor” log as the initial clue. Determine why the measurement is not returned and whether the behavior is expected; done means the cause and a verified correction or clear compatibility requirement are established.
