browser action "type" requires text

Error message

browser action "type" requires text

What it means

Validation error from the browser action resolver in resolveTool: the 'type' action maps to browser_type and must carry the text to type into the focused page element. It fires when the text field is absent, not a string, or a zero-length string, meaning a keystroke-injection request with no payload.

Solutions

1. Pass text as a non-empty string, e.g. {action:"type", text:"hello"}.
