Photoshop Beta 27.3 regression: scripting “Place Embedded” fails (works in 27.2)

Hi Adobe Community,

I’m reporting what looks like a regression in Photoshop (Beta) 27.3 affecting scripting.

Issue

After updating from Beta 27.2 → 27.3, my JSX scripts started failing consistently when using Place Embedded via scripting (the executeAction call with the "Plc " event). The script retries 3 times and then fails with the same error.

What I see

A dialog appears:

• “Error during execution of Script 4: Error: Place Embedded failed after 3 attempts for file: …”

(I’m attaching a screenshot of the error dialog.)

Expected behavior

The file should be placed/embedded into the current document as it did before.

Actual behavior

In Beta 27.3 the scripted Place Embedded fails, even though:

• the file exists,

• it’s not locked,

• it has a normal size (e.g. ~450 KB),

• I can open and view the same file in Photoshop with no issues.

Regression confirmation

I installed Photoshop Beta 27.2 again and everything works immediately with the same files and the same scripts. So the only change causing the failure is the update to Beta 27.3.

Environment

• OS: Windows 11

• Workflow: JSX script, batch process; uses executeAction(charIDToTypeID("Plc "), ...) (Place Embedded)

• Input files: JPG/PNG (issue occurs regardless—files that worked yesterday in 27.2 fail today in 27.3)

If anyone from Adobe can confirm/triage this, I’m happy to provide the relevant script snippet or a minimal reproducible sample.

Thanks!
Ivan
