Bump fee on a bitcoin stuck transaction

Hello, I have a transaction stuck for over a week because I entered a very low fee. The transaction has the RBF flag enabled, and I entered the following command in my Umbrel node console to increase the fee:

sudo ~/umbrel/scripts/app compose lightning exec lnd lncli wallet bumpfee --sat_per_byte 30 < txid >:0

But when I hit enter, I get the following error:

[lncli] rpc error: code = Unknown desc = the passed output does not belong to the wallet

Clearly, this doesn’t make sense because I used my node’s mempool and was able to verify that the < txid > is correct
Can you help me solve this problem?"
