"Collection id not found" Error for custom collection contract

[rjoshi-deq]

We are using Rarible ERC1155 Factory contract to deploy our own ERC1155 contract, when we try to mint NFTs on this custom contract using the Rarible SDK it looks for a collection id corresponding to this contract but it is unable to find any.

We are unable to find any SDK method or any API to create a collection id for our custom deployed contract. How can I generate a collection id and avoid this error.

PS:- Besides the Factory contract we have also tried OpenZeppelin ERC1155 to deploy our custom contract. This contract also encounters the same error.
