This was a bug with pyparsing 3.0.0-3.0.6. I reverted our version for now, but we should be safe again after 3.0.7 is released.

[someone-au]

Perfect thanks for the update.

[cinderblock]

I'm seeing what I think may be the same bug. I have a lot of logs but I just see logs that are over 7 hours old. For a frame, as the page loads, I see the most recent logs, but then they get filtered away to only show old ones.

I was experiencing this issue back in December on version 3.2.7, then the issue was gone for a while. Now, with version 3.3.8, it is back. Assuming this is still based on the pyparsing bug that [gazpachoking] mentioned. Just not sure why it came back. Validated that pyparsing module is version 3.0.7 which was expected to address the problem.

Same. Version 3.3.8 and API 1.8.0. Log tab display no log but disconnect. Already try to delete sqlite file and log what I think would rebuild cache or something cause this issue but cannot fix

[frankyw]

Same. Version 3.3.8 and API 1.8.0. Log tab display no log but disconnect.

Same version, same problem (blank log tab, but does show "streaming" with a blank page)

Tried pyparsing 3.0.7 and 3.0.8, same result.

[shotfirer]

Is there any news about this issue? No changes in 3.3.9

[frankyw]

@gazpachoking any thoughts on this? The issue remains with pyparsing 3.0.7, 3.0.8 and now I have confirmed with 3.0.9 on Flexget 3.3.9

[kristenmills]

I opened a pull request to lock the pyparsing version back to 2.4.7 which should fix the issue while i look into what changes with pyparsing@3

[kristenmills]

Pinned the version of pyparsing back to 2.4.7. The fix will be in the next flexget release. Will update when that
is published (roughly 16 hours from now)
Flexget/Flexget@ad8d076

[kristenmills]

Sorry entirely forgot to update once it was published but @frankyw or @shotfirer can you confirm it's working in a version of flexget v3.3.11 or later?

[frankyw]

@kristenmills yep all working fine on 3.3.12 👍🏼

[kristenmills]

Perfect thanks. I'm gonna close this out then.
