Highcharts.AST.allowedAttributes

Hello,

How can I use Highcharts.AST.allowedAttributes with /usr/local/bin/highcharts-export-server (v4) please ?

I tryed using --customCode "AST.allowedAttributes.js"
but it does not work.

The file contains:
Highcharts.AST.allowedAttributes.push('border');
Highcharts.AST.allowedAttributes.push('align');
Highcharts.AST.allowedAttributes.push('bordercolor');
Highcharts.AST.allowedAttributes.push('zIndex');
Highcharts.AST.allowedAttributes.push('bgcolor');
Highcharts.AST.allowedAttributes.push('cellpadding');
Highcharts.AST.allowedAttributes.push('cellspacing');
Highcharts.AST.allowedTags.push('center');
Highcharts.AST.allowedAttributes.push('center');

On the Dockerfile:
WORKDIR /node-export-server
ADD ["AST.allowedAttributes.js","/node-export-server"]
RUN chown -R node /node-export-server && \
chmod 644 AST.allowedAttributes.js

The command line :
/bin/docker run -u 0:0 -v /apache_sites/jbm:/apache_sites/jbm --rm --tmpfs=/run highcharts_es timeout 10 /usr/local/bin/highcharts-export-server --allowCodeExecution true --infile /apache_sites/jbm/b.json --outfile /apache_sites/jbm/web/img/toto.png --resources '[]' --customCode AST.allowedAttributes.js --width 720 --height 320 --scale 1.2 --logLevel 4
