Description

Chainlink node dashboard for job runs debugging at the following URL:

http://localhost:6688/runs/1

fails to load with a blank screen while the rest of the dashboard loads with no issues.

When inspecting the empty page, the following HTML error appears:

I am reading through these other issues noted here:

https://github.com/smartcontractkit/chainlink/issues/14556#issuecomment-2374155934

Maybe there is a syntax error in the TOML job specification causing this?

I think I found the issue.

I have a comment in section

observationSource

for

submit_tx

that I don't think is being detected as a comment. I tried to created a comment with character

#

Are comments allowed in this section? I will remove this comment:

submit_tx    [type="ethtx" to=<OPERATOR_ADDRESS> data="$(encode_tx)"] # Operator.sol contract address.

to have:

submit_tx    [type="ethtx" to=<OPERATOR_ADDRESS> data="$(encode_tx)"] 

then see if it works.
