Error: Call to a member function getParameter() on null in Drupal\panels_ipe\Form\PanelsIPEBlockPluginForm->getContextsForPath() (line 505 of /var/www/docroot/modules/contrib/panels/panels_ipe/src/Form/PanelsIPEBlockPluginForm.php)

Changes from MR make sense
It will avoid error message about getParameter()

Could it be because of wrong variables ?

Neither of the patches worked for me. Attached a patch I now use which solves the problem for me.
I hope this helps to solves the problem.

Patch in #7 is working for me
(aligning with changes in page_manger since patch from Path has unnecessary query appended is committed)

joseph.olstad → made their first commit to this issue’s fork.

None of the patches worked on Drupal 10.3.12, Panels 4.8, Panelizer 4.5.0.

Simple `Powered By Drupal` block was added to new empty panel and error occurred when saving panel:

When adding Content -> ID block (to simply show node id) after clicking `Add` block button:

Same for me, but a combination of #7 and #8 works. In addition we have to consider that the change from page_manager_page to _page_manager_page only has been introduced recently: 🐛 Path has unnecessary query appended. Fixed . I try to create a new patch by tomorrow.

Haven't looked closely however I did look at the pipeline. In the unit tests I'm seeing two additional fails with the latest commit. Not sure if it's related but could be.

@joseph.olstad, view modes should not be affected by this if they weren't by patch #7 and #8 individually. In the MR I see two older commits merged by you starting with "Issue #3470578 and Issue #3465159" and two older commits starting with "Issue #3456918". So the branch dedicated for this issue (3465159-error-call-to) contains changes for two other issues as well. Maybe the additional test failures are related to those commits, or maybe there are incompatible changes on the main branch and the working branch 3465159-error-call-to should be rebased to incorporate those changes?

Hi everyone, we needed to fix this for a project so I've created a new branch and a MR that includes changes from #2, #7 and #8.
Also changing the version to latest 8.x-4.x dev (since the MR branch is based on that branch).

Updated the fork to include the latest security changes.

Tested the patch on a brand new D10 test site using 8.x-4.x-dev and on a project using the 8.x-4.9 → .

I upgraded to panels 4.9.0 and I'm using panelizer 4.4, although I also tried 4.5.
After applying the patches to avoid getParameter() errors, when creating a new block or using an existing one, ONLY ON NEW NODES, when trying to save changes with panel ipe I get a 500 error on URLs like the following: http://localhost:8080/admin/panels_ipe/variant/panelizer_default/*node:3... and the following response:
The website encountered an unexpected error. Try again later.

This doesn't happen in version 4.7.0, but it does starting with 4.8.0. What's the cause and how can I fix it?
