Mirador error: SyntaxError: Unexpected token < in JSON at position 0

[Matteo]

Hi everyone,
I used Omeka S with my college.
When I used Mirador for viewing images the plugin show me this error in Chrome: Mirador error: SyntaxError: Unexpected token < in JSON at position 0, when I used a Safari browser show me this: SyntaxError: The string did not match the expected pattern.

Only Mirador show me this problem because UniversalViewer works without problems.
This page for example: Natura Naturata · Le piante · Unife Virtual Heritage

Thanks!

Hello Matteo,

I took a look and it seems like the problem is that the URL https://virtualheritage.unife.it/iiif/1/4104/info.json does not exist. However, these ones work: https://virtualheritage.unife.it/iiif/3/4104/info.json https://virtualheritage.unife.it/iiif/2/4104/info.json

I think that this means that Mirador is trying to load IIIF resources using v1, but your IIIF module only supports versions of the protocol 2 or higher.

What versions of the Mirador Viewer and IIIF Server modules are you using?

[Matteo]

Thank you for your response.
The version of IIIF server is 3.6.5.3 and the version of Mirador is 3.3.7.15.

What do you recommend that I do?

Thanks!

My guess, the link to your manifest is wrong.
I checked the page:

the link to the manifest is set to:
https://virtualheritage.unife.it/iiif/2/set/4103

but it should be: https://virtualheritage.unife.it/iiif/2/4103
Then I can see you scan e.g. with universalviewer

[Matteo]

Really thanks!

But how can I integrate the correct manifest in the Mirador module?
Sorry but I don’t understand…

[dan]

Could you switch to universalviewer just for testing? Then you could proof if there is an error or misconfig in the iiifserver. Otherwise the error is caused by mirador.

[Matteo]

In this page (Browse page) I can see Mirador and UniversalViewer without problem, but if I insert the form in any page, it reports the problem to me.
Example: Botanica · Benvenuto · Unife Virtual Heritage

[dan]

The example page is really a “page”, or? Not a item-show.phtml template.
Did yo try to add other manifest into your example

The modules are all up to date I assume? Unfortunately I do not really know how to find the error either.

[Matteo]

Yes the page is part of the original site and yes by inserting other manifest Mirador works without problems.

I tried working on the IIIF server module and now I get this screen and not the images.

Your version of iiifserver is old. Can you try the last one (3.6.6.7)?

[Matteo]

Yes Thanks!
I solved by inserting a link and not the Mirador form directly.
For example: Loder · Benvenuto · Unife Virtual Heritage
