New Issue

Blender Version

Broken: 4.2+
Worked: 4.1

Short description of error

The insert_keyframe method now can throw python exceptions, which is a regression because it already has a boolean return value. This affects rigify rigs.

Exact steps for others to reproduce the error

# Blender 4.1.1
>>> C.object.keyframe_insert('location', options={'INSERTKEY_AVAILABLE'})
False

# Blender 4.2-beta
 >>> C.object.keyframe_insert('location', options={'INSERTKEY_AVAILABLE'})
Traceback (most recent call last):
  File "<blender_console>", line 1, in <module>
RuntimeError: Error: Could not create 3 F-Curve(s). This can happen when only inserting to available F-Curves.

Or to see the original issue:

Load the attached blender file.
Click the "Toggle Pole" button in the panel on the right.

Can confirm the change in behavior.

Getting the following:

Error: Exception: Error: Could not create 1 F-Curve(s). This can happen when only inserting to available F-Curves.

I managed to reduce the test case to reproduce this API change to a oneliner that works with the default blend file:

# Blender 4.1.1
>>> C.object.keyframe_insert('location', options={'INSERTKEY_AVAILABLE'})
False

# Blender 4.2-beta
 >>> C.object.keyframe_insert('location', options={'INSERTKEY_AVAILABLE'})
Traceback (most recent call last):
  File "<blender_console>", line 1, in <module>
