[bug]: `itest error from [node:Bob]` when bob is not even part of the test, but I still get a PASS and exit status 0

When running

make itest icase=test_custom_channels_liquidity

I get

itest error from [node:Bob]: receive topology client stream got err:graph subscription err: rpc error: code = Unknown desc = malformed header: missing HTTP content-type
    harness.go:444: finished test: , start height=438, end height=495, mined blocks=57
--- PASS: TestLightningTerminal (93.07s)
    --- PASS: TestLightningTerminal/test_custom_channels_liquidity (93.07s)
PASS

which seems contradictory that I get a PASS and exist status 0, when there is an error message itest error from [node:Bob]: receive topology client stream got err:graph subscription err: rpc error: code = Unknown desc = malformed header: missing HTTP content-type.

I've added a lot of breakpoints and I don't think this error is coming from within the function testCustomChannelsLiquidityEdgeCases. Also, bob doesn't seem to be even part of testCustomChannelsLiquidityEdgeCases.

I don't think we should get any errors if a PASS is returned, but somehow we do here.

Actually, this seems to come with all FAILed cases too, but the error doesn't seem to be related to the actual failure (which becomes extra confusing).
