[SOLVED] xk6 Prometheus remote write fails with go error

xk6 Prometheus remote write fails with go error

I am trying to use xk6 prometheus remote write to send k6 data.

In GitLab pipeline trying to install xk6 on golang image but it fail with go error with some version issue.

GitLab job

run:k6:
  stage: run
  environment: DEV
  variables:
    GIT_CHECKOUT: "false"
  image:
    name: golang
  needs:
    - job: build:k6
  script:
    - go install go.k6.io/xk6/cmd/xk6@latest
    - xk6 build --with github.com/grafana/xk6-output-prometheus-remote@latest
    - ./k6 run -o experimental-prometheus-rw --tag testid=test build/script.js
  artifacts:
    reports:
      junit: junit.xml
  when: manual

Getting below error while running pipeline

Tried to check with different version of golang image like 1.19 and xk6 version also but same error persist.

Solution

Here is the reason of failure pipeline was having a variable like:

variables:
  K6_VERSION: "0.44.1"

which was used when I run

xk6 build --with github.com/grafana/xk6-output-prometheus-remote@latest

No idea how this was overriding, but after renaming/removing this variable it works.
