How would possibly I repair Core Lightning’s fundchannel: “They despatched ERROR channel ***: funding failed on account of inner error”

After working lightning-cli join 03a93b87bf9f052b8e862d51ebbac4ce5e97b5f4137563cd5128548d7f5978dda9 ldafy556bsfgjuxodwbt6naw3r67yt5jztajlpluqawhowt324s3rzqd.onion:9735 I obtained from this output from the peer with whom I selected to open a channel:

{
   "id": "03a93b87bf9f052b8e862d51ebbac4ce5e97b5f4137563cd5128548d7f5978dda9",
   "options": "8000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000020008a8a51a1",
   "route": "out",
   "tackle": {
      "sort": "torv3",
      "tackle": "ldafy556bsfgjuxodwbt6naw3r67yt5jztajlpluqawhowt324s3rzqd.onion",
      "port": 9735
   }

Assuming that establishing a connection over TOR succeded I then run lightning-cli -k fundchannel id=03a93b87bf9f052b8e862d51ebbac4ce5e97b5f4137563cd5128548d7f5978dda9 quantity=16777215 announce=false feerate=3000perkb and obtained the next output:

{
   "code": -1,
   "message": "They despatched ERROR channel ****************************************************************: funding failed on account of inner error",
   "knowledge": {
      "id": "03a93b87bf9f052b8e862d51ebbac4ce5e97b5f4137563cd5128548d7f5978dda9",
      "technique": "fundchannel_start"
   }
}

I then went down the listing of onion lightning nodes and tried the identical with BOTLZ and obtained
comparable output after working fundchannel.
I’ve sufficient onchain BTC, listfunds returns

      }
   ]
}

I’ve channels open with only one peer and when making an attempt to open with them I don’t get the identical output, channel opening succeeds offered the payment is excessive sufficient.
