tagort214:

It seems we are receiving malformed JSON from the director here as the decoding throws a syntax error.

We should have a look at the JSON result the director provides for the particular directory you are
trying to list in webui by using bvfs API commands (https://docs.bareos.org/DeveloperGuide/api.html#bvfs-api) in bconsole.


In bconsole please do the following:


1. Get the jobid of the job that causes the described issue, 142 in this example. Replace the jobid from the example below with your specific jobid(s).

*.bvfs_get_jobids jobid=142 all
1,55,142
*.bvfs_lsdirs path= jobid=1,55,142
38 0 0 A A A A A A A A A A A A A A .
37 0 0 A A A A A A A A A A A A A A /


2. Navigate to the folder which causes problems by using pathid, pathids will differ at yours.

*.bvfs_lsdirs pathid=37 jobid=1,55,142
37 0 0 A A A A A A A A A A A A A A .
38 0 0 A A A A A A A A A A A A A A ..
57 0 0 A A A A A A A A A A A A A A ceph/
*

*.bvfs_lsdirs pathid=57 jobid=1,55,142
57 0 0 A A A A A A A A A A A A A A .
37 0 0 A A A A A A A A A A A A A A ..
56 0 0 A A A A A A A A A A A A A A groups/
*

*.bvfs_lsdirs pathid=56 jobid=1,55,142
56 0 0 A A A A A A A A A A A A A A .
57 0 0 A A A A A A A A A A A A A A ..
51 11817 142 P0A V9T EHt CcR A A A 8AA BAA L4 BhLhQA BhLhP/ BhLhP/ A A C group_aa/

Let's pretend group_aa (pathid 51) is the folder we can not list properly in webui.


3. Switch to API mode 2 (JSON) now and list the content of folder group_aa (pathid 51) to get the JSON result.

*.api 2
{
  "jsonrpc": "2.0",
  "id": null,
  "result": {
    "api": 2

Do you get valid JSON at this point as you can see in the example above?
Please provide the output you get in your case if possible.



Note:

You can substitue step 3 with sth. like following if the output is too big:

[root@centos7]# cat script
.api 2
.bvfs_lsdirs pathid=51 jobid=1,55,142
quit

[root@centos7]# cat script | bconsole > out.txt

Remove everything except the JSON you received from the .bvfs_lsdirs command from the out.txt file.

Validate the JSON output with a tool like https://stedolan.github.io/jq/ or https://jsonlint.com/ for example.
