Intermittent Datahub 5.3 Error : Could not transform by expression delete

[Former Member]

Hi,

I sometime see this error during publication phase and don't know how to overcome this.

I am using Datahub 5.3 version and this error doesn't occur always. It very intermittent and don't know when and why it occurs.

All the mappings and definition of target items are correct and it works without any issue most of the time.

Appreciate your inputs.

Full error here: Log

Suresh, One recommendation that I have for you is to upgrade to the latest version of the Data Hub just released (5.3.0.9-RC1). You may be missing some fixes that came out as patches in the last year or so. I would also recommend changing the log level to trace, and examining if the additional information gives you any more insight in your problem.

Best recommendation would be to upgrade to the latest version of the DH (5.7), but I realize that's not always feasible.

Alright Thanks for the suggestion Rafal. We can do this minor upgrade and check if it helps.

Hi Rafal,

The latest Hybris Commerce suite in 5.3 version is 5.3.0.8 and it contains "datahub-webapp-5.3.0.0-RC9.war" file. Can you help me to find out where the version that you mentioned above can be downloaded?

Cheers.

It turns out that the ECP version 5.3.0.9 has not been released yet (although the patch for the Data Hub is ready). However, upon closer examination of what was fixed in that patch, I doubt that it would help you in any way. I apologize for any inconvenience this might have caused.

Using trace level might be the next thing to try.

Suresh,

It looks like 5.3.0.9 ECP patch has not been released yet (even though the Data Hub patch is ready). However, I have looked at the bug fixes that we have addressed in there, and it does not look like it would help you. I apologize for any inconvenience.

Thank you very much for your swift responses Rafal.

[rafal_gdowski]

No problem. Looks like the patch will not be released until January, but nonetheless, I don't think it would help you much. Any luck looking at trace logs?
