Apollo recurring crawler issues

Hi,

 

Have you met with problem with recurring crawling (minutely, hourly, daily....)? Every inteval job ends with error:

 

java.lang.NullPointerException
at com.erdas.apollo.dmbl.crawling.process.directory.FileCollectionCrawler.execute(FileCollectionCrawler.java:55)
at com.erdas.apollo.dmbl.crawling.process.directory.FileCollectionCrawler.execute(FileCollectionCrawler.java:36)

I am using Erdas Apollo Pro 2020 (2018 EP04 has the same issue), Windows Server 2019 and OJDK 11.0.5

Re: Apollo recurring crawler issues

I could not duplicate this issue in APOLLO 2020, but I do notice the following issue (AP-11116)

 

[How to repeat]
[1] Set crawler job (FIVEMINUTELY as interval)
[2] The job run immediately, and images get crawled correctly.
[3] Add new images in the same folder, and wait for next Run date.

 

[What was expected to happen]
New images will be crawled at next run date

 

[What did happen]
Nothing happened.

 

Hope it helps.
