Invalid multimap flag entry. No '=' found: io.noticeable.newspage.soy.functions.ContainsFunction

Using the latest open source version 2023-07-19 that include security fixes, compiling a soy template breaks with this error message:

Invalid multimap flag entry.  No '=' found: io.noticeable.newspage.soy.functions.ContainsFunction,io.noticeable.newspage.soy.functions.DefaultAvatarFunction,io.noticeable.newspage.soy.functions.ExcerptFunction,io.noticeable.newspage.soy.functions.GetFunction,io.noticeable.newspage.soy.functions.HtmlFunction,io.noticeable.newspage.soy.functions.Iso8601Function,io.noticeable.newspage.soy.functions.LabelsFunction,io.noticeable.newspage.soy.functions.LabelClustersFunction,io.noticeable.newspage.soy.functions.MarkdownFunction,io.noticeable.newspage.soy.functions.NullOrBlankFunction,io.noticeable.newspage.soy.functions.PhraseFunction,io.noticeable.newspage.soy.functions.ReplaceUrlPlaceholdersFunction,io.noticeable.newspage.soy.functions.Rfc822Function,io.noticeable.newspage.soy.functions.TimestampFunction,io.noticeable.newspage.soy.functions.UniqueJoinFunction,io.noticeable.newspage.soy.functions.UrlFunction

Here is snippet of a soy template that shows how the contains custom function is used:

{template Publication}
    {@inject baseUrl: trusted_resource_uri}
    {@inject assetsUrl: trusted_resource_uri}
    {@inject newspage: map<string, ?>}
    {@inject project: map<string, ?>}
    {@inject queryParameters: map<string, list<string>>}
    {@inject requestUri: string}

    {@param publication: map<string, ?>}

    {let $labels: labels($project, $publication) /}

    {call Layout}
        {param canonicalUrl kind="text"}{nullOrBlank($publication['seo']['canonicalUrl']) ? '' : $publication['seo']['canonicalUrl']}{/param}
        {param metaDescription kind="text"}{contains($publication, 'seo', 'meta', 'description') ? get($publication, 'seo', 'meta', 'description') : excerpt($publication)}{/param}
...
{/template}

I guess a breaking change has been introduced since the last release but I cannot understand what it is based on the error message. Any idea?

Hmmm... Do you have any more details you could share? Like repro steps or at least the command you run to see that error?
