I’m trying to update item description using MCP from cursor. It uses set_item_description_content mutation to perform this operation, when description (in GFM format) has tables it returns

Error: Failed to execute GraphQL operation: Internal server error (details: {"code":"INTERNAL_SERVER_ERROR"})

Field	Value
Item	`11874250264` (ESB-058)
Markdown length	27,476 characters
SHA-256 of `variables.markdown`	`88a84fa727adbbd136da9c9e37a74ea00a454eb0d6ef1e48752375c4319392e5`
Mutation	`set_item_description_content(item_id: $itemId, markdown: $markdown) { success error }`

If request embeds tables in a code block it doesn’t fail.
