getFullNumber not working for country code 972

Hello,

getFullNumber function is always giving only country code for +972.
For example my phone number +972555555555, library says phone number valid. But when I run getFullNumber function it only says 972. I tried with another (real) phone numbers with same country code but results are same only gives country code.

I tried randomly +49, +93, +1, +61 these are working fine.

How can I fix this issue?

首先定位 getFullNumber 的实现及其使用的国家号码处理逻辑。重现报告中的 +972555555555 案例，将其与正常工作的国家代码示例进行比较；当 +972 能够返回完整号码且不使这些案例发生回归时，即可认为 issue 已完成。
