And because generative-ai-hub-sdk[all] (4.1.1) depends on langchain (>=0.3.0,<0.4.0), generative-ai-hub-sdk[all] (>=4.0.0,<4.3.1 || >4.3.1,<4.4.3 || >4.4.3,<4.10.2 || >4.10.2,<4.12.4 || >4.12.4,<5.0.0) requires langchain (>=0.3.0,<0.4.0).
And because generative-ai-hub-sdk[all] (4.3.1) depends on langchain (>=0.3.0,<0.4.0)

Because no versions of langchain-hana match >1.0.0,<1.1.0
 and langchain-hana (1.0.0) depends on langchain (>=1.0.0,<2.0.0), langchain-hana (>=1.0.0,<1.1.0) requires langchain (>=1.0.0,<2.0.0).
Thus, langchain-hana (>=1.0.0,<1.1.0) is incompatible with generative-ai-hub-sdk[all] (>=4.0.0,<5.0.0).
So, because doc-indexer depends on both generative-ai-hub-sdk[all] (>=4.0.0,<5.0.0) and langchain-hana (>=1.0.0,<1.1.0), version solving failed.
