Issue with sendBocReturnHash API

I'm trying to get the transaction hash after sending a transaction using TonConnect UI.
When calling the sendBocReturnHash endpoint, I'm getting the following error:

Error message:
{
"ok": false,
"error": "LITE_SERVER_UNKNOWN: cannot apply external message to current state : External message was not accepted\nCannot run message on account: inbound external message rejected by transaction 4C6FE61A4B7925532DEE47DEED8367FB9E918D4B32A9B9EC270BEF9D9C65CA13:\nexitcode=133, steps=49, gas_used=0\nVM Log (truncated):\n...SIGNU\nexecute PUSHCONT x28945F0ADB31E1F2C087\nexecute IFNOT\nexecute XCHG s2\nexecute NOT\nexecute XCHG2 s0,s7\nexecute AND\nexecute THROWIF 132\nexecute XCPU s2,s5\nexecute EQUAL\nexecute THROWIFNOT 133\ndefault exception handler, terminating vm with exit code 133\n",

Expected behavior:

• Should return the transaction hash

What I've tried:

• Added delay after transaction
• Verified BOC format
