Gitlab CI: api trigger with axios call not working when using variables

Question

Without the variables the server call works and gitlab is starting the pipeline.

But when I add variables to that call, it errors: "variables needs to be a map of key-valued strings".

This is my code:

    axios
      .post(`https://gitlab.myurl.com/api/v4/projects/${projectId}/trigger/pipeline`, {
        ref: branch,
        token: token,
        variables: { STAGING_AREA: 'testing1', NOTIFY_STATUS: true, SLACK_USER_ID: 'xxxxx' }
      })
      .then(res => {
        console.log('pipeline started:', res.data.web_url);
      })
      .catch(error => {
        console.error('errorMessage', error);
      });

What is the correct syntax for passing variables?

Answer 1

I was doing one thing wrong.

NOTIFY_STATUS: true

It seems that true can only be passed as a string:

NOTIFY_STATUS: 'true'

After this edit my code worked just fine.
