Appium use storeVisualization throw cannot be cast to java.lang.String Execption

Support

I was using appium to do some image check with opencv4nodejs

there is my code:

SimilarityMatchingOptions opts = new SimilarityMatchingOptions();
opts.withEnabledVisualization();
SimilarityMatchingResult res = driver.getImagesSimilarity(new File(“1.jpg”), new File(“2.jpg”), opts);
res.storeVisualization(new File(“3.jpg”));

it will throw “com.google.common.collect.Maps$TransformedEntriesMap cannot be cast to java.lang.String”

then i try delete “res.storeVisualization(new File(“3.jpg”));”, which is

SimilarityMatchingOptions opts = new SimilarityMatchingOptions();
opts.withEnabledVisualization();
SimilarityMatchingResult res = driver.getImagesSimilarity(new File(“1.jpg”), new File(“2.jpg”), opts);

then everything is fine,

so the problem is “res.storeVisualization(new File(“3.jpg”))”,but i didn’t know why, i copy the code in https://github.com/cloudgrey-io/appiumpro/blob/master/java/src/test/java/Edition098_Visual_Testing_1.java ,line 95-100

I think there’s no reason to be wrong

sorry for my broken english

This was happening due to a server bug. Try appium@beta

so is the only way to fix that?
