Tasker upgrade broke Run Shell (Error: 134)

[Sal Lusso]

Running Tasker 5.1m on Oreo 8.0.0.

A Run Shell action that used to work on previous Tasker/Android versions now gets an error:

04.55.44/Variables doreplresult: |%sqlite3 %dbfile "select sql from sqlite_master where type = 'table' and tbl_name = 'synclogs'"| -> |/data/data/com.keramidas.TitaniumBackup/files/sqlite3 /data/data/dk.tacit.android.foldersync.full/databases/foldersync.db "select sql from sqlite_master where type = 'table' and tbl_name = 'synclogs'"|

Running the same command in Terminal after "su" returns a valid result, no error. Command:

/data/data/com.keramidas.TitaniumBackup/files/sqlite3 /data/data/dk.tacit.android.foldersync.full/databases/foldersync.db "select sql from sqlite_master where type = 'table' and tbl_name = 'synclogs'"

Apparently error 134 means the program was aborted (received SIGABRT). But I have no idea how to look into this further since it works fine in Terminal.

Hi there. Do you know on which version it worked?

It was at least working on my last device: Tasker 4.9u4 on Android 6.0.1.

But in fact, I just tested and Tasker 5.1m also works on Android 6.0.1!

The error comes on Tasker 5.1m on Android 8.0.

[João Dias]

Can you try with the beta? 

[Sal Lusso]

It works with the beta!

Do I need to be rooted for this to work? This task generates a security
exception:

Sorry, which of those actions shows that error? And yes, you need to be rooted to list settings.

Are there any Run Shell command that work without root? If so, is there a list somewhere of command that do work?

[João Dias]

Very weird how that action would give you an error about User permissions... About no-root commands, sorry, I really don't know which they are myself. :)

Sure there are, but that is ultimately dependent on Android, not Tasker. Anything you can run in Terminal without superuser rights, should also work in Tasker without root.
