Exception while running JSON Database upgrade tool

[semperor]

I have updated from the last 4th version to the current 5th version using sudo apt update and sudo apt upgrade.

The addon package was updated. The openhab package was not, as Java was still version 17. I then removed version 17 (sudo apt purge openjdk...) and installed version 21.

This time the openhab package was installed. When executing the database update, the following error occurred:

I also get an exception from the upgradetool, though the cause seems to be different:

EDIT: after adding unit metadata to the above items (+ one more) the exception was gone. and after it ran through once, the deserialization error was gone as well.

@boehan Thanks for the report, I will create a fix. Another regression from #4855 :-(

Anyhow, this seems to be a different issue and unrelated to the initial report in this issue.

[holgerfriedrich]

@jimtng Could you please have look?
I already have addressed the second issue reported in the comment, but the initial one is related to the Yaml upgrader.

This is a weird error, it shouldn't have happened. I haven't been able to reproduce it either.
@semperor can you try running the tool manually?

Something like java -jar /openhab/runtime/bin/upgradetool.jar --command yamlTagsListToMap --conf /path/to/openhab/conf/ --force

[openHAB] WARNING: internal database upgrade tool failed.

[semperor]

This is a weird error, it shouldn't have happened. I haven't been able to reproduce it either. @semperor can you try running the tool manually?

Something like java -jar /openhab/runtime/bin/upgradetool.jar --command yamlTagsListToMap --conf /path/to/openhab/conf/ --force

I'd love to, @jimtng . Unfortunately, I can't seem to select the correct OpenHAB configuration file. I found the following files that I think are suitable for ".../openhaven/conf." Could you tell me which one is correct?

1. /etc/openhab/services/runtime.cfg
2. /usr/share/openhab/runtime/services.cfg
3. /var/lib/openhab/config/profile.config/var/lib/openhab/etc/profile.cfg
4. /var/lib/openhab/config/profile.config
5. /var/lib/openhab/config/org/openhab/services.config
6. /var/lib/openhab/config/org/openhab/runtime.config

[jimtng]

I'd love to, @jimtng . Unfortunately, I can't seem to select the correct OpenHAB configuration file. I found the following files that I think are suitable for ".../openhaven/conf."

It's the /etc/openhab, so:

java -jar /openhab/runtime/bin/upgradetool.jar --command yamlTagsListToMap --conf /etc/openhab --force

In fact it doesn't matter you can even use --conf /tmp. The problem occurred during the class instantiation before scanning the directory.

Note it will give you some warning about userdata not given, that can be safely ignored.

[yndtrud]

In my case the update crashes because of an attempt to parse a UNIT from STATEDESCRIPTION when the element has no UNIT in the METADATA, but has a STATEDESCRIPTION

I ran the debugger and found the problem.

openhab-core/tools/upgradetool/src/main/java/org/openhab/core/tools/internal/ItemUnitToMetadataUpgrader.java

// LINE161: UnitUtils.parseUnit(pattern); - exception

Unit<?> stateDescriptionUnit = UnitUtils.parseUnit(pattern);
if (stateDescriptionUnit != null) {
    unit = stateDescriptionUnit.toString();
}

One of the elements causing the exception, without unit:madforce_systeminfo_sys_cpu_temperature in meta data

  "stateDescription:madforce_systeminfo_sys_cpu_temperature": {
    "class": "org.openhab.core.items.Metadata",
    "value": {

@yndtrud thanks, will be fixed by #4924

Everyone else, could you please execute the same command and tell me whether the same exception happened?

java -jar /openhab/runtime/bin/upgradetool.jar --command yamlTagsListToMap --conf /tmp --force (the directory doesn't matter. Point it to any empty directory.)
