500 Error editing row with binary column using datasette-write-ui

[logicalpath]

Using Firefox 124.0.2 (64-bit) on an M3 Mac

Using datasette version 1.0a13 with these plugins:

[
{
"name": "datasette-media",
"static": false,
"templates": false,
"version": "0.5.1",
"hooks": [
"register_routes"
]
},
{
"name": "datasette-render-images",
"static": false,
"templates": false,
"version": "0.4",
"hooks": [
"render_cell"
]
},
{
"name": "datasette-write-ui",
"static": true,
"templates": true,
"version": "0.0.1a9",
"hooks": [
"extra_template_vars",
"register_routes"
]
}
]

Clicking on edit in any row that has an image, throws 500 and uncaught promise in console.
