Summary

When I perform dataLayer.push() in a gtm event, the value sent is different from the value picked up by GTM.

Additional information

next v15.2.4

At GTM Preview

1st time
  window.dataLayer = window.dataLayer || [];
  window.dataLayer.push({
    event: 'button_click_event',
    variable_1: 1,
    variable_2: [1],
  });

2nd time
  window.dataLayer = window.dataLayer || [];
  window.dataLayer.push({
    event: 'button_click_event',
    variable_1: 2,
    variable_2: [1],
  });

3rd time
  window.dataLayer = window.dataLayer || [];
  window.dataLayer.push({
    event: 'button_click_event',
    variable_1: 3,
    variable_2: [1],
  });

4th time
  window.dataLayer = window.dataLayer || [];
  window.dataLayer.push({
    event: 'button_click_event',
    variable_1: 2,
    variable_2: [1],
  });


5th time
  window.dataLayer = window.dataLayer || [];
  window.dataLayer.push({
    event: 'button_click_event',
    variable_1: 1,
    variable_2: [2,3],
  });


At this time, the API call on the GTM preview debug screen is as follows:
  window.dataLayer = window.dataLayer || [];
  window.dataLayer.push({
    event: 'button_click_event',
    variable_1: 1,
    variable_2: [2,3],
  });

However, the delivered tag is as follows:
  window.dataLayer = window.dataLayer || [];
  window.dataLayer.push({
    event: 'button_click_event',
    variable_1: 1,
    variable_2: [1,2,3],
  });




The values ​​in the API call and the tag values ​​that are fired are different, is there a cache or something?
