PE-ARG-5000

Error message

No generate content model is selected in the configuration

What it means

GenerateContentCommand.selectModel (GenerateContentCommand.java:62-72) throws this when the action configuration's formData does not contain the GENERATE_CONTENT_MODEL key. This method is called during createExecutionUri (line 58-59) to build the API URL with the model name in the path. Without a model, the URI cannot be constructed. Categorized as PLUGIN_EXECUTE_ARGUMENT_ERROR (PE-ARG-5000).

Solutions

Select a model from the model dropdown in the Google AI query editor (e.g., gemini-2.5-pro).
If using JS mode, ensure the bound expression returns a valid model identifier string in the generateContentModel form field's data key.
Verify the form data includes the 'generateContentModel' key with a nested 'data' field containing the model name.
Re-save the query after selecting the model to persist the form data.

Defensive patterns

Strategy: validation

Validate before calling

// Ensure a model is selected before executing
if (!form.generateContentModel || !form.generateContentModel.data) {
  showAlert('Please select a Google AI model before running the query', 'error');
} else {
  await googleAiQuery.run();
}

Prevention

Always select a model from the dropdown when creating a Google AI query.
Verify the form data includes the generateContentModel key with a nested data value.
Use validateRequest-equivalent checks in a pre-execution JS callback.

When it happens

Trigger: The Google AI query's form data is missing the 'generateContentModel' key entirely, or actionConfiguration/formData is null. The three-way null check (actionConfiguration != null, formData != null, containsKey(GENERATE_CONTENT_MODEL)) at lines 63-65 fails on the third condition. This fires during URI construction, before the request body is even built.

Common situations: 1) User creates a new Google AI query but forgets to select a model from the dropdown. 2) The model field was cleared or never populated after switching from another command type. 3) JS mode is enabled and the bound expression returns undefined/null for the model field. 4) Form data structure changed due to a UI/plugin update.
