Reasons for receiving the error message, "Model tier_index error", when using the "v2.product.add_model" API

Reasons for receiving the error message, "Model tier_index error", when using the "v2.product.add_model" API

1. The option corresponding to "tier_index" does not exist.

For example:

Seller has defined two colors, with details as below:

Action: If you call the "v2.product.add_model" API and add tier_index[2], "v2.product.add_model" API will return an error with the message, "Model tier_index error".

Reason: "tier_index" overflow

Solution:

Step 1: Please call the "v2.product.get_model_list" API to view the current "option_list" with "tier_index" information. Step 2: If you need to add a third color, you need to call the "v2.product.update_tier_variation" API to add options, and then call the "v2.product.add_model" API.

2. The option corresponding to "tier_index" already exists.

For example:

Seller has defined two colors, with details as below:

Action: If you call the "v2.product.add_model" API and add tier_index[0], "v2.product.add_model" API will return an error with the message, "Model tier_index error".

Reason: tier_index[0] already has model information

Solution:

Step 1: Please call the "v2.product.get_model_list" API to view the current "option_list" with "tier_index" information.

Step 2: If you want to update the tier_index[0] model information, please call the "v2.product.update_model" API.

3.The "tier_index" array is incorrect.

For example:

Seller has defined two colors, with details as below:

Action: If you call the "v2.product.add_model" API and add tier_index[0,0], "v2.product.add_model" API will return an error with the message, "Model tier_index error".

Reason: "tier_index" should not be a two-dimensional array because only 1 tier variation is defined

Solution:

Step 1: Please call the "v2.product.get_model_list" API to view the current "option_list" with "tier_index" information.

Step 2: If you want to define 2-tier variation, please call the "v2.product.init_tier_variation" API instead.
