[Bug] Incompatible Language version 15. Must be between 13 and 14

[Prodesire]

Bug Description

When iac-code generates Terraform templates, it throws an error: Incompatible Language version 15. Must be between 13 and 14. This appears to be a version incompatibility between tree-sitter and the language grammar packages (e.g., tree-sitter-language-pack).

The root cause is likely that tree-sitter 0.24.0 only supports language ABI versions 13–14, but the installed language grammar (from tree-sitter-language-pack) was compiled with ABI version 15, which requires a newer version of tree-sitter.

Related upstream issue: tree-sitter/py-tree-sitter#355

Steps to Reproduce

1. Run iac-code
2. Enter the following prompt:

生成terraform模版，在阿里云上，region为cn-beijing.

* 创建一个vpc，cidr为172.16.0.0/16.

* 每个vpc内有三个vswitch，vswitch都在cn-beijing-k。
1. vswitchC，cidr是172.16.1.0/24。
2. vswitchPH, cidr是172.16.2.0/24。这个vswitch的eni绑定安全组，连通策略为组内隔离，允许源是172.16.2.0/24目的端口是4789的udp报文进入，允许源是172.16.2.0/24目的端口是179的tcp报文。
3. vswitchSG，cidr是172.16.3.0/24。这个vswitch的eni绑定安全组，连通策略为组内隔离，允许源是172.16.3.0/24目的端口是4789的udp报文进入，允许源是172.16.2.0/24目的端口是179的tcp报文。

* 创建四个ecs：
1. ecs1~ecs4的主网卡都在vswitchC中，ecs1的hostname是ecs10，ip是172.16.1.10和；ecs2的hostname是ecs11，ip是172.16.1.11。ecs3的hostname是vxlan-gateway-PH，ip是172.16.1.6，ecs4的hostname是vxlan-gateway-SG，ip是172.16.1.7。
2. ecs1还有两个辅助网卡，辅助网卡1在vswitchPH中，ip是172.16.2.10；辅助网卡2在vswitchSG，ip是172.16.3.10。
3. ecs2还有两个辅助网卡，辅助网卡1在vswitchPH中，ip是172.16.2.11；辅助网卡2在vswitchSG，ip是172.16.3.11。
4. ecs3还有一个辅助网卡，辅助网卡在vswitchPH, ip是172.16.2.6。
5. ecs4还有一个辅助网卡，辅助网卡在vswitchSG中，ip是172.16.3.7。

* ecs1的初始化脚本（init脚本），通过"自定义数据"传入：
0. 等待eth1和eth2网卡被挂载，且为up
1. 配置vxlan接口vxlan0，没有remote不绑定dev，ip地址为10.0.1.10，up

* ecs2的初始化脚本（init脚本），通过"自定义数据"传入：
0. 等待eth1和eth2网卡被挂载，且为up
1. 配置vxlan接口vxlan0，没有remote不绑定dev，ip地址为10.0.1.11，mac地址为12:00:01:0:1:0B，up

* ecs3的初始化脚本（init脚本），通过"自定义数据"传入：
0. 等待eth1，且为up

* ecs4的初始化脚本（init脚本），通过"自定义数据"传入：
0. 等待eth1，且为up

3. Wait for iac-code to generate the Terraform template
4. Observe the error during code generation/parsing

Expected Behavior

iac-code should generate the Terraform template without any tree-sitter version compatibility errors.

Actual Behavior

The following error is displayed in red during the response:

错误：Incompatible Language version 15. Must be between 13 and 14

The error occurs after iac-code reads reference files and attempts to generate/parse the Terraform code.

Operating System

macOS

Python Version

3.12.7

iac-code Version

0.3.0

Additional Context

Installed tree-sitter related packages:

• tree-sitter: 0.24.0
• tree-sitter-language-pack: 0.7.3
• tree-sitter-languages: 1.10.2

The version constraint in pyproject.toml is tree-sitter>=0.23, which allows installing 0.24.x. However, tree-sitter-language-pack 0.7.3 appears to ship grammars compiled with ABI version 15, which requires tree-sitter>=0.25.

Possible fix: either pin tree-sitter to a compatible version (e.g., >=0.23,<0.25) or upgrade to tree-sitter>=0.25 to support ABI version 15.

[guima-why]

Fixed in PR #62. Terraform generation/parsing flows no longer fail due to the tree-sitter ABI mismatch error (Incompatible Language version 15. Must be between 13 and 14).

PR: #62

Verified with make translate, make format, make lint, and make test (3777 passed, 244 warnings).

Closing as completed.
