# cat /etc/sysconfig/airsonic
# Set the location of the standalone war to use
JAVA_JAR=/var/airsonic/airsonic.war

# Set any java opts separated by spaces
JAVA_OPTS=-Xmx3048m -Xms3048m

# Set a different location for airsonic home.
# If this path is /var/libresonic or even contains "libresonic",
# the data from a previous libresonic can be used as is (i.e. without
# renaming libresonic.properties,db/libresonic*,etc
AIRSONIC_HOME=/var/airsonic

# Change the port to listen on
PORT=14040

# Change the path that is listened on
CONTEXT_PATH=/

# Add any java args. These are different than JAVA_OPTS in that
# they are passed directly to the program. The default is empty:
#JAVA_ARGS=

# Note that there are several settings for spring boot, not explicitly listed
# here, but can be used in either JAVA_OPTS or JAVA_ARGS. The full list
# can be found here:
# https://docs.spring.io/spring-boot/docs/1.4.5.RELEASE/reference/htmlsingle/#common-application-properties
# For example to set debug across the board:
#JAVA_ARGS=--debug

# Or to change the ip address that is listened on:
#JAVA_ARGS=--server.address=127.0.0.1

JAVA_ARGS=--logging.level.org.airsonic=info

Failed to auto-import playlist /data/mstream_data/_MusicPlaylists/(a) My A Collection.m3u

java.lang.NullPointerException: null

[litebito]

I'm migrating to a new server: CentOS 9 Stream, and Postgres as a DB backend
On this new server setup, the error does not show up, and the Imported playlist shows all (7861) songs.
(so no java.lang.NullPointerException: null error during import for now on the new server)

Did you manage to capture any additional logging information? It would help to list out the rest of the log from that timeframe. Unfortunately that error message shown is too generic to know what could be causing the problem.

Hi,
There was not a lot of logging before the error.
I'll try to enable debugging if I see the error again
