smartagent/prometheus-exporter unable to parse '/u'

[bexu0500]

Hi, I'm using the smartagent/prometheus-exporter receiver to scape on prometheus federate endpoint.
Getting below error for some of the jobs.
"error": "text format parsing error in line 1767: invalid escape sequence '\u'",

it appears caused by \u in the raw data

rest_client_requests_total{job="kubernetes-apiservers",instance="10.0.10.9:6443",code="\u003cerror>",method="POST"} 2 1707787782477

Is there anyway I can work around this? it seems impact received all the metrics in the job group not just the few problematic ones.

receiver config:
smartagent/prometheus-exporter:
- type: prometheus-exporter
host: 10.215.12.35
port: 8481
metricPath: /select/0/prometheus/federate?match[]={job=~"kubernetes-apiservers"}
