start sync: error executing tar: : command terminated with exit code 126

[AskAlice]

What happened?

running a docker image built with a custom script, that handles some aspect of tagging the image, it does pair up with the image but it then returns

[0:sync] Starting sync...
[fatal]  start sync: unable to start sync: start sync: error executing tar: : command terminated with exit code 126

What did you expect to happen instead?

sync to work

How can we reproduce the bug? (as minimally and precisely as possible)

@AskAlice thanks for creating this issue! Looks like the tar command is not present in the target container, but it is required for the sync to function correctly. Could that be the case?

I am having the same issue

[fatal]  start sync: start sync: error executing tar: : command terminated with exit code 126

tar is available in the target container:

Maybe its a special version of it?

For me the issue was a Pod deployment with multiple containers without setting dev.sync.containerName=xxx
