Gnosis Safe SDK – Resolving ‘Cannot Estimate Gas’ on Ethereum Mainnet vs Rinkeby

I am trying to execute a gnosis safe transaction on Ethereum mainnet but consistently this error –

error: cannot estimate gas; transaction may fail or may require manual gas limit (error={\"code\":3,\"message\":\"execution reverted: GS026\",\"data\":\"0x08c379a0000000000000000000000000000000000000000000000000000000000000002000000000000000000000000000000000000000000000000000000000000000054753303236000000000000000000000000000000000000000000000000000000\"}, method=\"estimateGas\", transaction={\"from\":\"0xf6754b8a58BFb62C89827bC31be363b608b39bE3\",\"to\":\"0xb76Bed0B12062F3668AfD7d300B2A193a297cee3\",\"data\":\"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\",\"accessList\":null}, code=UNPREDICTABLE_GAS_LIMIT, version=providers/5.5.3)",
    "level": "error"
}

The same code is working fine on Rinkeby but the same code giving this error on the mainnet. Not able to understand the reason.

Currently having an issue with this transaction
