DAM not showing thumbnail for replace action for type .svg image

[kchaura]

Hi Everyone.

DAM not showing thumbnail for replace action for type .svg image

1. Observed when “replacing” .svg/.jpg files with the same name.

2. Thumbnail image is not reflected

3. In the properties, the type is not prefilled

There is no issue Whenever uploading the image first time but while replacing the same .svg/.jpg files image, thumbnail is not being generated and type is not prefiles . It is also deleted all the existing metadata . please check the below snapshots for your reference. 

First time upload : There is no issues

Metadata

Second time upload the same image with the same name with replace option: Thumbnail not updating and type not updating and deleting the metadata.

is the .svg having correct properties?

can you open the .svg image in browser and check properties? width / height etc?

Thanks @SureshDhulipudi Yes that is fine no issues with that. Actually i used multiple .svg images  and everything is working fine in all the lower environment except prod.

Hi @kchaura 

1. Install the "SVG Thumbnail Provider" package in your AEM instance. This package provides a thumbnail provider for SVG images that can generate thumbnails for SVG images.

2. After installing the package, go to the "Thumbnail" tab in the DAM asset properties dialog for the SVG image.

3. Click the "Generate" button to generate a thumbnail for the SVG image.

4. Save the asset properties.

5. Try replacing the SVG image again and check if the thumbnail is generated correctly.

If the above steps do not resolve the issue, you can try the following workaround:

1. Before replacing the SVG image, make a copy of the existing asset and rename it to a temporary name.

2. Replace the original SVG image with the new SVG image.

3. Go to the asset properties for the new SVG image and copy the metadata from the temporary asset.

4. Delete the temporary asset.

This workaround should preserve the metadata for the SVG image and generate a thumbnail for the new SVG image.

Thanks @Raja_Reddy  Thanks for the respond . I already tried this , actually issues with .svg and .png and this is noticed only in prod with replace the same asset and other environment is working as expected so there might be issue from OOTB workflow end. Once i try to De-activate the Update Asset - Modification workflow  from the launcher then i am able to reproduce the same issue on local environment but the thing we should not de-activate it.

Regarding thumbnails:

Requesting you to please verify the workflows that are getting triggered.

- On upload

- On replace

Also, compare the workflows between the instances where its working as expected and the PROD instance.

• Are all the AEM instances on the same version ?
• Do you expect any code differences between environments?
• Are you noticing any errors in Broser or AEM logs?

Thanks @aanchal-sikka  for the respond . I checked and compare all the workflow related to DAM updates from lower environments to prod  and i found one launcher config diff. that i already tried to replicate to dev but it is not working. Whenever i am trying to de-activating  the "Update Asset - Modification" workflow from the launcher then i am able to reproduce the exact  issue on lower environments but the thing is we should not deactivate it right?. Do you think this issues occured due to DM config as recently we did  this configuration but that is available in all the environments, but issues in prod only thats why not sure why this is happening. Please find my comments inline . Thank you.

• Are all the AEM instances on the same version : Yes
• Do you expect any code differences between environments: NO, It may some config and i checked and mentioned above.
• Are you noticing any errors in Broser or AEM logs? Yes . While uploading and replacing the asset. I noticed the below errors. 
• Errors:

@kautuk_sahni Thanks Kautuk. Still no luck and it is not working. Need more information.It seems issues with the "Update Asset - Modification" workflow whenever i am de-activating this workflow i am able to reproduce the same issue in the lower environment but this workflow is active in prod and once we are replacing the asset then thumbnail is not generating  and all the metadata is being deleted.   Thank You.
