Claude reading my Miro Flow chart

I have the pro version of Miro and took months to build out a flow chart or survey mapping out the questions I ask in a sales consultation. However when I gave Claude access in order to build out an app it responded “it's returning 500 unsupported items and no readable content. This typically means the board is built entirely with sticky notes, shapes, and connectors (which is standard for Miro flowcharts), but the MCP reader can only parse Docs, Tables, and text frames.” Where do I go from here? Is there an easy way inside Miro to revise it so Claude can read and understand the flow?
