c-clips faill as "blob unavailable" but are readable with JCASScript.jar

[lriva94]

Hello,
at a customer site I have more than 7000 c-clips failing copy from Centera to ECS with a 'blob unavailable' error message, but when I use the ClipToFile command of JCASScript.jar the ClipToFile command works successfully.

Here is the stack trace:

2024-07-05 08:10:17 WARN [sync-pool-4-t-32] SyncTask: O--! object 3A08XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXAJTPLL failed

Looking at code show that this error is raised when the tag.BlobExists() method return false, but when I navigate inside the c-clip using JCASScript it says blobexists is true.

Here is the c-clip eclipcontents structure:

<eclipcontents>
<STORAGE_CENTER>
<eclipblob md5="3SEXXXXXXXXXXXXXXXXXXXXX7U3" size="991863" offset="0"/>
</STORAGE_CENTER>
</eclipcontents>

What should be the conditions where the ECSSync function returns something different as JCASScript ?

Thanks for your help.
