TikTok Ads Invalid Metric Fields Error

What this article covers

This article explains how to understand and fix the following TikTok Ads error in Catchr:

What the error means

The most important part of the error is this section:

This means one of the fields used in the query cannot be combined with the other selected fields.

In most cases, the issue is not that the field is unavailable.

The issue is that TikTok Ads does not allow that field to be queried alongside the other selected metrics or dimensions.

Why this is confusing

The error message shows the field ID, not the field name shown in the Catchr interface.

So users see:

• engagements

But in Catchr, they may only recognize the field by its visible label:

• Clicks (All)

As a result, users often do not know which field to remove.

How to identify the field

To find the matching field name, check the TikTok Ads field list.

In Catchr's TikTok Ads metrics page:

• Clicks (All) is listed

• Its field ID is “engagements”

How to fix the error

Step 1: Identify the field ID shown in the error

Read the error message carefully and find the field ID listed in Invalid metric fields.

In this example, the invalid field is:

- engagements

Step 2: Match the field ID with the field name

Open the TikTok Ads metrics page and search for the field ID.

In this case:

- engagements = Clicks (All)

Step 3: Remove the field from the query

Once the field is identified, remove it from the query and try again.

If the query works after removing that field, the issue was the field combination.

If you need that field specifically

If your goal is to extract that field, keep it in the query and remove other fields one by one until the query works.

This helps you identify which metric or dimension is incompatible with it.

In practice, the solution is usually:

• remove the problematic metric

• or remove the incompatible dimension

• then rerun the query

Concrete example

A user wanted to query these metrics:

• Impressions

• Spend

• Clicks (All)

With these dimensions:

• Campaign

• Ad group

• Ad

• Gender

The query failed because:

• Clicks (All) uses the field ID engagements

• That field is not compatible with Gender in this query setup

To fix the query, the user has two options:

• remove Gender

• or remove Clicks (All) and run a separate query for it

Recommended troubleshooting method

When you get this error:

1. Read the field ID shown in the error

2. Look up the field ID in the TikTok Ads metrics list

3. Identify the visible field name

4. Remove that field and test the query again

5. If you need the field, remove other fields until you find the incompatible combination

Best practice

When building TikTok Ads queries with many metrics and dimensions:

• Start with a smaller query

• Confirm it works

• Then add fields progressively

This makes it much easier to identify which field combination causes the error.

Summary

This error does not usually mean the field is missing.

It usually means:

• The field exists

• But TikTok Ads does not allow it to be combined with the other selected fields

In this example:

• Engagements is the field ID

• The visible field name is Clicks (All)

The resolution is to remove the incompatible field combination and retry the query.
