IT34467: GATEWAYSCRIPT ERROR MIGHT OUTPUT NAN INSTEAD OF MULTIPLE PERCENT CHARACTERS

Fix packs for DataPower Gateway version 2018.4.1
Fix packs for DataPower Gateway version 10.0.x

APAR status

• Closed as program error.

Error description

• The user attempted to print a URL query params string escaped
  by "querystring.escape" to log using IBM DataPower
  GatewayScript "console.error" but hit unexpected "NaN" results
  after the second escaped character (here the ampersand).
  // good log: a%3D1
  console.error(´good log: ${querystring.escape('a=1')}´);
  // bad log: a%3D1 NaN%3D2
  console.error(´bad log: ${querystring.escape('a=1&b=2')}´);
  In contrast, writing the escaped string to a context variable
  or to output shows the escaping itself is fine.
  // good output: a%3D1%26b%3D2
  session.output.write (´good output:
  ${querystring.escape('a=1&b=2')}´);
  

Local fix

• A workaround is to replace the percent character as '%%'.
  // replaced log: a%3D1%26b%3D2
  console.error(´replaced log:
  ${querystring.escape('a=1&b=2').replace(/%/g, '%%')}´);
  

Problem summary

• GatewayScript querystring.escape fails for more than 2 URI
  params creating NaN
  

Problem conclusion

• Fix is available in 2018.4.1.14, 10.0.1.1
