fix(connector-besu): do not crash if ledger unreachable - send HTTP 503
Primary Changes --------------- 1. Yarn patch to [email protected] so that it does not crash nodejs process Without the catch block, the rejection is an unhandled rejection that bubbles up to the top of the callstack where NodeJS itself catches it and then crashes the entire process. (used to be that it just logged a warning but since some of the newer versions it crashes which allows us to find these bugs in our code / library's code) 2. It is returning a 503 instead of a 500 3. Added a static retry-after header value of 5 seconds 4. Added test case in test-ledger which has run-transaction at the end that is expected to give error 503 when the backing ledger is unavailable Fixes: hyperledger-cacti#3406 Co-authored-by: Peter Somogyvari <[email protected]> Signed-off-by: ruzell22 <[email protected]> Signed-off-by: Peter Somogyvari <[email protected]>
