Hi @ajimae I don't think this retry is enough. As I wrote in the issue (https://github.com/commercetools/nodejs/issues/1743#issuecomment-1028794106), it should be able to retry also at network errors OR at 4xx errors if it contains a particular error message. Also we should be able to define the retry rules. Basically it should work the same as in the old sphere-node-sdk (https://github.com/commercetools/sphere-node-sdk/blob/master/src/coffee/repeater-task-queue.coffee#L7).

Hi Lam,

Thanks for the feedback, I will work to include retries for the network errors and also specific error messages. For the retry rules, we already have this defined and configurable, except you have a rules that is not part of what we currently have, then please you can as well let us know.

Thanks

I really can't say because we need @jenschude to approve.
