<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>After composer update, GraphQL server stops working, with error:<br>
`Syntax Error: Invalid number, expected digit but got: "N"`</p>
<p>In GraphQL Server, editing the Server with GraphQL Compose, and visiting tabs "Explorer" or "Voyager" doesn't work, with the same error as above. The "Validation" tab displays `Invalid number, expected digit but got: "N"`</p>
<p>However, changing the GraphQL Server Schema to "Composable Schema" allows to visit tabs "Explorer" and "Voyager" (although without data, as I don't have a manual "Composable Schema".<br>
(Note: seems like the webonyx-php Explorer has changed, as its layout is very different from before)</p>
<p>I'm guessing that there was a change on the Schema, and that the "GraphQL Compose schema" needs some adjustment?<br>
It can also be a bug from Drupal GraphQL module itself, but I'm not really sure, as changing the above seems to touch the issue.</p>
<p>The full error, as displayed on Drupal Log Messages:</p>
<p>GraphQL\Error\SyntaxError: Syntax Error: Invalid number, expected digit but got: "N" in GraphQL\Language\Lexer->readDigits() (line 439 of /vendor/webonyx/graphql-php/src/Language/Lexer.php).</p>
