deepakwipro Could you please post the code that you've written to assemble the deploy contract request and the logs of the API server when the 127 exit code is returned?

I found some solution regarding this issue:-
I made change at line 207 in node_modules/@hyperledger/cactus-plugin-ledger-connector-fabric/dist/lib/main/typescript/plugin-ledger-connector-fabric.js.
I replaced await ssh.putDirectory(tmpDirPath, remoteDirPath); with await ssh.putDirectory(tmpDirPath, remoteDirPath,{concurrency: 1});

deepakwipro You are the best, thank you so much for coming up with the fix at the same time. 🙂
I'll commit the fix ASAP and we'll have a release with it hopefully next week in the form of 1.0.0-rc.3
Please keep an eye out for the release and the release notes to know when the fix is published onto npm.

I am Deepakwipro. I tried on remoteVM then it again throws same error. Last time, i tried to test it on localhost only so may be for that it started working after adding concurrency:1. Pls look into this issue for remoteVM,
