invalid width for attribute view column

Error message

invalid width for attribute view column [%s]

What it means

While building the width map inside setAttributeViewColsWidth, each value in the Data map must be a string (the CSS width). If any value is a number, boolean, or nested object, the assertion value.(string) fails and the error names the offending column ID.

Solutions

1. Convert every width value to a string, including units (e.g. "200px")
2. Locate the column named in the [%s] interpolation and fix that entry
3. Validate the width object client-side before queuing the transaction

Example fix

// before
{"20240101xxxx": 200}
// after
{"20240101xxxx": "200px"}

for (const [id, w] of Object.entries(widths)) {
  if (typeof w !== "string") throw new Error(`width for column ${id} must be a string, got ${typeof w}`);
}

const isWidthEntry = (e: [string, unknown]): e is [string, string] => typeof e[1] === "string";

try { await setAttrViewColWidth(op); } catch (e) { const m = String(e).match(/invalid width for attribute view column \[(.+)\]/); if (m) { widths[m[1]] = String(widths[m[1]]) + "px"; } else throw e; }

When it happens

Trigger: POSTing a setAttrViewColWidth operation where one entry is {"colId": 200} (number) instead of {"colId": "200px"}.

Common situations: Scripts computing widths numerically and forgetting to stringify; plugins copying widths from DOM px values as numbers; schema drift between client versions.

Understand the failure class

Background: "Must be a positive integer", "Invalid value", "Unsupported": the invalid-argument-value error family, when a library rejects the value you pass — this error's family across 35 libraries.
