Briefly, this error occurs when Elasticsearch is unable to compile a script file due to syntax errors, missing dependencies, or incorrect file permissions. To resolve this issue, you can check the script for syntax errors and correct them. If the script relies on external dependencies, ensure they are properly installed and accessible. Lastly, verify that Elasticsearch has the necessary permissions to read and execute the script file.

Log Context
Log “compiling script file [{}]” classname is ScriptService.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :
} else {
try {
//we don't know yet what the script will be used for; but if all of the operations for this lang
// with file scripts are disabled; it makes no sense to even compile it and cache it.
if (isAnyScriptContextEnabled(engineService.types()[0]; engineService; ScriptType.FILE)) {
logger.info("compiling script file [{}]"; file.toAbsolutePath());
try(InputStreamReader reader = new InputStreamReader(Files.newInputStream(file); Charsets.UTF_8)) {
String script = Streams.copyToString(reader);
CacheKey cacheKey = new CacheKey(engineService; scriptNameExt.v1(); null; Collections.emptyMap());
staticCache.put(cacheKey; new CompiledScript(ScriptType.FILE; scriptNameExt.v1(); engineService.types()[0]; engineService.compile(script; Collections.emptyMap())));
scriptMetrics.onCompilation();
