SignerListSet Payload Error

I'm currently trying to sign a transaction by providing this payload:

{
"txjson": {
"Flags": 0,
"TransactionType": "SignerListSet",
"Account": "rh5QhvyqTg2QTZdciXkDdEnDmJfuQvmuF7",
"Fee": "12",
"SignerQuorum": 5,
"SignerEntries": [
{
"SignerEntry": {
"Account": "rPT1Sjq2YGrBMTttX4GZHjKu9dyfzbpAYe",
"SignerWeight": 2
}
},
{
"SignerEntry": {
"Account": "rPd9oB2Kdot9HSsXSeFYpKZUV3vDsBzv73",
"SignerWeight": 1
}
},
{
"SignerEntry": {
"Account": "rhx2Ru7kb33w8UP2iRCCpVYPdUGyKAdhMZ",
"SignerWeight": 2
}
}
]
}
}

I'm receiving this error in Logs:
Internal error code 1217
Error (detail) message No permission to create this type of sign request. Contact Xumm Support (in-app).

I'm able to sign this transaction locally using this exact object without the "txjson". So the problem can't be from the object format. Is there limitations to what type of transactions or fields we can pass as a payload?

Thank you,
